- Nurse Kealani Kellye, a recurring character in the 4077th (appearing in 164 episodes), was played by Kellye Nakahara. A warm character, she had more to say than the other nurses. She is often seen dancing with Radar, and later, Charles. The first name "Kealani" was never used in the series. On several occasions, David Ogden Stiers and Loretta Swit have referred to her as "Nurse Nakahara" and "Lieutenant Nakahara", respectively.
- Jeff Maxwell appeared as the bumbling Pvt. Igor Straminsky in 75 episodes. In his earlier appearances, he was the camp cook's aide, complaining that, despite not cooking the food (SSG Pernelli was the cook, not revealed until season 9 as described below), he still had to listen to everyone's gripes about it. He was often the target of Hawkeye's wrath because of the terrible food, and the recipient of his "river of liver and ocean of fish" rant in "Adam's Ribs". His bumbling even gained the ire of Father Mulcahy, when he creamed the fresh corn Mulcahy grew in "A War for All Seasons". In at least two episodes, he was called a sergeant by Major Burns. In another episode, Burns asks his name and he replies "Maxwell," the actor's actual surname. Burns then replies with that name.
- Roy Goldman appeared in 35 episodes as Corpsman Roy Goldman.

Zale's name is mentioned for the final time in "Yessir, That's Our Baby".
- G. W. Bailey played the perpetually lazy Staff Sgt. Luther Rizzo, who headed the camp motor pool, in 14 episodes.
- Enid Kent played Nurse Peggy Bigelow in 14 episodes. She was quite often the target of Hawkeye's flirtations. In "They Call the Wind Korea", she gets injured by a falling water tower and is treated by the 4077th. In "Goodbye, Farewell, and Amen", when various members of the 4077th announce postwar plans, she blandly recounts her days as a nurse both in World War II and in Korea and simply says, "I've had it."
- Dr. Sidney Freedman, Major, a psychiatrist, was played by Allan Arbus, who appeared 12 times. In his first appearance, his name was Dr. Milton Freedman, but was subsequently changed. Dr. Freedman played a major role in the two-hour final episode.
- Colonel Flagg, a paranoid and jingoistic counterintelligence officer prone to using aliases, was played by Edward Winter. He appeared six times (and the actor appeared once as a very similar intelligence officer named Halloran).
- Marcia Strassman played nurse Margie Cutler six times during the show's first season. Her last appearance was in the episode "Ceasefire".
- Herb Voland appeared seven times as Henry Blake's commander, Brigadier General Crandall Clayton.
- G. Wood appeared three times as Brigadier General Hammond, the same role he played in the movie.

- Pat Morita appeared twice as Capt. Sam Pak of the Republic of Korea Army.
- Karen Philipp (singer with Sergio Mendes & Brasil 1966, 1967–70) appeared twice as Lt. Maria 'Dish' Schneider during the first season.

- Robert Alda, Alan Alda's father, appeared twice as Maj. Borelli, a visiting surgeon.
- Catherine Bergstrom appeared twice as Peg Hunnicutt, B.J.'s wife, back in the U.S.
- Lt. Col. Donald Penobscot appeared twice (played by two different actors), In "Margaret's Marriage" (#5.24), Penobscot was played by Beeson Carroll, and was her fiancé at the time (they were married during the episode). In "The M*A*S*H* Olympics" (#6.10), he appears as her husband, he takes part in a M*A*S*H Olympics; he is played by Mike Henry.
- Staff Sgt. "Sparky" Pryor, a friend of Radar and Klinger, was the telephone operator usually called by the 4077th MASH. He was seen only once, played by Dennis Fimple, in Tuttle (season 1, episode 15), but was sometimes faintly heard on the phone when he yelled.
- Sal Viscuso and Todd Susman played the camp's anonymous public address system announcer throughout the series. This character (who is never seen on camera) broke the fourth wall only twice, in the episodes "Pilot (M*A*S*H)" (1.1) and "Welcome to Korea" (4.1), both times while introducing the regular cast members. Both Viscuso and Susman appeared onscreen as other characters in at least one episode each.
- Eileen Saki appeared in seven episodes as Rosie, the owner and head bartender at Rosie's Bar, which was frequented by the regular characters. Her first appearance on the show, however, was as the madam of a brothel which was occupying a much-needed hut in the episode "Bug Out". Rosie had previously been played by Shizuko Hoshi (in "Mad Dogs and Servicemen") and Frances Fong (in "Bug Out" and "Fallen Idol") before Saki assumed the role.
- Timothy Brown appeared as Capt. Oliver Harmon 'Spearchucker' Jones in six season-1 episodes as a captain who lived with Pierce, Burns, and McIntyre in the "Swamp".
- Val Bisoglio appeared in three episodes as Staff Sergeant Salvatore Pernelli, the actual mess cook for the 4077th. His first appearance was in season 9's "The Life You Save", followed by two appearances in season 10, "Twas the Day After Christmas" and "A Holy Mess".

Actors with multiple roles
This section does not cite any sources. (May 2013) (Learn how and when to remove this template message)
Several guest stars made appearances as multiple characters:
- Hamilton Camp appeared twice, first as the insane Cpl. "Boots" Miller in "Major Topper" (episode 6.25), and again as a film distributor named Frankenheimer in "The Moon is Not Blue" (11.8).
- Dennis Dugan appeared twice, as O.R. orderly Pvt. McShane in 3.20, "Love and Marriage", and again in 11.11, "Strange Bedfellows", as Col. Potter's philandering son-in-law, Robert "Bob" Wilson.
- Gary Burghoff was the only actor to ever appear simultaneously on the show with himself. He played Radar O'Reilly throughout the show, and in episode 4.15 "Mail Call... Again", he watched a home movie sent to him in Korea in which he played his own mother. Father Mulcahy remarks, "Radar certainly bears a striking resemblance to his mother!"
- Tim O'Connor appeared as wounded artillery officer Col. Spiker in "Of Moose and Men" (4.12), and as visiting surgeon Norm Traeger in "Operation Friendship" (9.10). Both characters were noticeably at odds with Hawkeye.
- Dick O'Neill appeared three times (each time in a different U.S. service branch): as Navy Rear Admiral Cox, as Army Brigadier General Prescott, and as Marine Colonel Pitts.
- Harry Morgan played both the 4077th's second beloved C.O. (Col. Sherman T. Potter) and the mentally unstable Major Gen. Bartford Hamilton Steele in the show's third season, in the episode "The General Flipped at Dawn". This last character was a reprise of his role as Major Pott in the 1966 movie, What Did You Do in the War, Daddy?
- Soon-Tek Oh appeared five times: twice as a North Korean POW (in 4.7, "The Bus", and 8.10, "The Yalu Brick Road"); once as a North Korean doctor (5.10, "The Korean Surgeon"); once as O.R. orderly Mr. Kwang (3.20, "Love and Marriage"); and once as a South Korean interpreter who poses as a North Korean POW (11.3, "Foreign Affairs").
- Philip Ahn appeared three times: episodes 4.19 ("Hawkeye"), 5.13 ("Exorcism"), and 6.9 ("Change Day"). Like Soon-Tek Oh, Ahn was one of the few Korean actors to play a Korean on M*A*S*H; most of the other "Korean" characters were played by either Japanese, Chinese, or Vietnamese ethnic actors. Ironically, Ahn played Japanese villains in World War II movies and Chinese characters on Bonanza and Kung Fu.
- Robert Karnes appeared twice: once as a colonel in 4.1 ("Welcome to Korea") and as a general in 6.4 ("Last Laugh").
- Clyde Kusatsu appeared four times: twice as a Korean bartender in the Officers' Club, once as a Chinese-American soldier, and once as a Japanese-American surgeon.
- Robert Ito played a hood who works for the black market in 1.2, "To Market, To Market", and a North Korean soldier disguised as a South Korean looking for supplies, in 5.10, "The Korean Surgeon".
- Keye Luke appeared three times. In "Patent 4077" (6.17), he played Mr. Shin, a local jewelry maker hired by the surgeons to make a new surgical clamp; in "A Night at Rosie’s" (7.24), he played Cho Kim, who ran a crooked craps game in the back room at Rosie’s Bar; and in "Death Takes a Holiday" (9.5), he played the headmaster of a local orphanage.
- Mako appeared four times, once as a Chinese doctor (3.2, "Rainbow Bridge"), once as a South Korean doctor (5.11, "Hawkeye Get Your Gun"), once as a South Korean officer (8.3, "Guerilla My Dreams"), and once as a North Korean soldier (9.1, "The Best of Enemies").
- Jerry Fujikawa appeared as crooked Korean matchmaker Dr. Pak in "Love and Marriage", as Trapper John's tailor in 3.3, "Officer of the Day", as an acupuncturist named Wu in 8.24, "Back Pay", as the Uijeongbu chief of police in "Rally Round the Flagg, Boys", and as "Whiplash Wang" in "Deal Me Out".
- John Orchard starred as Australian anesthetist Ugly John in the first season, and later appeared in 8.13 as disgruntled and drunken Australian MP Muldoon, who has an arrangement with Rosie the barkeeper: he takes bribes (in the form of liquor in his "coffee" mug) to "look the other way." Orchard was actually English, so adopted an Australian accent and some Australian colloquialisms for his persona. He also normally wore an Australian-style "slouch" hat.
- Richard Lee Sung appeared 10 times as a local Korean who often had merchandise (and in one case, real estate) he wished to sell to the hospital staff; he once sold a backwards-running watch to Major Burns and he also tried to help Corporal Klinger lose his money in a game of craps in A Night at Rosie's.
- Jack Soo, known for his role as Barney Miller's Sgt. Nick Yemana, appeared twice, once as black-market boss Charlie Lee, with whom Hawkeye and Trapper made a trade for supplies in "To Market, To Market" (1.2), and in "Payday" (3.22) as a peddler who sold Frank two sets of pearls: one real, the other fake.
- Ted Gehring appeared twice: in 2.12, as moronic Supply Officer Major Morris, who refuses to let the MASH doctors have a badly needed incubator, and in 7.6, as corrupt supply NCO Sgt. Rhoden.
- Eldon Quick appeared three times, once as a finance officer and twice as Captain Sloan.
- Edward Winter appeared as an intelligence officer named "Halloran" in 2.13, and in six episodes as Colonel Flagg (although Halloran may have been one of Flagg's numerous and often mid-episode-changing aliases). Given a comment he makes to Sidney Freedman about the two playing poker together (a reference to Winter's appearance as Halloran) this seems to be likely.
- Shizuko Hoshi appeared four times: once as "Rosie" of "Rosie's Bar" in episode 3.13, "Mad Dogs and Servicemen"; and three times as the mother in different Korean families in "Hawkeye" (4.18), "B.J. Papa San" (7.16), and "Private Finance" (8.8).
- John Fujioka, who played the uncredited role of a Japanese golf pro in the movie, appeared three times in the series. The first time was in "Dear Ma" (1975) as Colonel Kim, the second time was in "The Tooth Shall Set You Free" (1982) as Duc Phon Jong, and the last time, he played a peasant in "Picture This" (1982).
- Stuart Margolin appeared twice, first as psychiatrist Capt. Phillip Sherman in season 1's "Bananas, Crackers and Nuts" (1.07), and again as plastic surgeon Major Stanley "Stosh" Robbins in season 2's "Operation Noselift" (2.18).
- Oliver Clark appeared twice. In "38 Across" (5.16), he played the part of Hawkeye's crossword-loving friend Lt. Tippy Brooks. In "Mail Call Three" (6.21), he played the part of 'the other' Captain Ben Pierce.
- Jeanne Schulherr appeared in season 3's "There Is Nothing Like a Nurse" as Frank Burns's wife, Louise (in a home movie), and in two other season-3 episodes as an unnamed nurse.
- Charles Frank appeared in season 5 as Capt. Hathaway in "Dear Sigmund", a pilot who admitted to not knowing the victims of his bombings from his plane, and appeared in season 6 as Lieutenant Martinson in "What's Up, Doc?", a troubled Yale graduate who finds himself in the infantry and holds Maj. Winchester Hostage at gunpoint.
- Kevin Hagen appeared twice. In "Some 38th Parallels" (4.20, 1976), he played the part of Colonel Coner, on whom Hawkeye drops garbage from an airborne helicopter. In "Peace On Us" (7.2, 1978), he played the part of red-haired Major Goss, sent to warn Hawkeye to stay away from the peace talks.
- Yuki Shimoda appeared three times. In "The Price" (7.18, 1979), he played the part of Cho Pak, a farmer who was a former Korean cavalry officer who steals Col. Potter's horse Sophie only because he is dying and wants one final chance to remember his military days. In "Yessir, That's Our Baby" (8.15), he plays a Korean consular officer who advises Hawkeye and B.J. that to allow an abandoned Amerasian infant to live in Korea would result in dire consequences. And, in "Oh, How We Danced" (9.14, which aired almost two months before his death in 1981), he plays the grandfather of a child patient of the 4077th who is a skilled harmonica player.
- James Carroll appeared twice, as an orderly in "Bug Out" and as a jeep driver who brought Major Winchester to the 4077th in "Fade Out, Fade In".
Notable actors and actor information
This section does not cite any sources. (May 2013) (Learn how and when to remove this template message)
- Antony Alda, Alan Alda's half-brother, appeared in one episode ("Lend a Hand") as Corporal Jarvis alongside both his brother and father (Robert).
- Robert Alda, Alan Alda's father, had guest appearances in two episodes, "The Consultant" and "Lend a Hand", the latter written by Alda himself. According to Alda, "Lend a Hand" was his way of reconciling with his father. He was always giving suggestions to Robert for their vaudeville act, and in "Lend a Hand", Robert's character was always giving Hawkeye suggestions. It was Robert's idea for the doctors to cooperate as "Dr. Right" and "Dr. Left" at the end of that episode, signifying both a reconciliation of their characters, and in real life, as well.
- While most of the characters from the movie carried over to the series, only four actors appeared in both: Gary Burghoff (Radar O'Reilly) and G. Wood (General Hammond) reprised their movie roles in the series, though Wood appeared in only three episodes. Timothy Brown (credited as "Tim Brown") played "Cpl. Judson" in the movie and "Spearchucker Jones" in the series. Corey Fischer played Capt. Bandini in the film and was the guitar-playing dentist "Cardozo" in the episode "Five O'Clock Charlie".
- Two of the cast members, Jamie Farr (Klinger) and Alan Alda (Hawkeye Pierce), served in the U.S. Army in Korea in the 1950s after the Korean War, Alda as a junior officer, Farr as enlisted. The dog tags Farr wears on the show are his actual dog tags. Farr served as part of a USO tour with Red Skelton. Furthermore, Wayne Rogers served as a Naval Reserve officer in the mid-1950s after the end of Korean War, and Mike Farrell (B.J. Hunnicut) served in the U.S. Marine Corps as a younger man from 1957-1960.
- Gary Burghoff's left hand is slightly deformed, with three smaller than normal fingers and slight syndactyly between the fourth and fifth digits, and he took great pains to hide or de-emphasize it during filming. He did this by always holding something (like a clipboard) or keeping that hand in his pocket. Burghoff later commented that his (Radar's) deformity would have made it impossible for him to be involved in active service. The deformity can be clearly seen at the very beginning of the pilot episode, when he is holding the football just before announcing the arrival of choppers. It is also visible at the end of "Images" (season 6, episode 9), when he is trying to lift weights.
- Most of the M*A*S*H main cast guest-starred on Murder, She Wrote (with the exceptions of Alan Alda, McLean Stevenson, and Gary Burghoff). Wayne Rogers made five appearances as roguish private investigator Charlie Garrat. David Ogden Stiers appeared three times as a Civil War-infused college lecturer and once as a classical music radio host. G.W. Bailey appeared twice as a New York City police officer. Larry Linville made two appearances as a police officer who was sure that Jessica was in the CIA. Harry Morgan appeared once in a cleverly cut episode that mixed with the 1949 film Strange Bargain in which Morgan had starred. William Christopher made an appearance as a murderous bird watcher. Jamie Farr appeared in two episodes, once as a hopeful new publisher for Jessica Fletcher, and again with Loretta Swit (she played a modern artist framed for murder). Mike Farrell appeared as a Senate hopeful.
- Through the series, several actresses play characters named Nurse Able or Nurse Baker, with widely varying personalities/roles. The characters' names were based on the old military phonetic alphabet.
- Sorrell Booke guest-starred as Brigadier General Barker in the episodes "Requiem for a Lightweight" and "Chief Surgeon Who?". Booke was a Korean War veteran who achieved greater fame as Boss Hogg in the Dukes of Hazzard television series.
- Ron Howard guest-starred as Marine Private Walter Peterson in the episode "Sometimes You Hear the Bullet". He is discovered to be underage and using his brother Wendell's identification, having come to Korea to impress his girlfriend. Hawkeye first gives the young soldier some sage advice about women, and then essentially lets him decide for himself whether he wants to go back to the States or stay in Korea. After losing his best friend Tommy Gillis, Hawkeye immediately reports the young soldier to the MPs, sending him back to America and to safety - with the Purple Heart Frank Burns put in for after his back pain.
- Leslie Nielsen guest-starred as Colonel Buzz Brighton in the episode "The Ringbanger". Because of his high casualty record, Hawkeye and Trapper try to get him sent back to America by convincing him that he is insane.
- Sal Viscuso is often credited as the sole PA announcer for the television series and even the film. Though he did serve as the voice of the PA announcer for a time, Todd Susman had the longest tenure. Neither actor's voice was heard in the film. Both actors appeared as other characters in various episodes.
- Art LaFleur appeared in one episode in season 9 ("Father’s Day") as an MP looking for the person(s) responsible for a stolen side of beef.
- Patrick Swayze appeared in one episode ("Blood Brothers") as Gary Sturgis, an injured soldier with a broken arm who is diagnosed with leukemia.
- John Ritter was in one episode ("Deal Me Out") early in his career, as a "shellshocked" soldier.
- Football player Alex Karras was in one episode ("Springtime") serving as Hawkeye's bodyguard after the doctor saves his life.
- Bruno Kirby (When Harry Met Sally, City Slickers) played Boone in the first episode. He can be seen tossing a football with Radar, and later helping to carry a drugged-out Major Frank Burns to a bed in post-op.
- Richard Herd appears in the season-9 episode called "Back Pay".
- Laurence Fishburne (CSI, The Matrix) appeared in the season-10 episode "The Tooth Shall Set You Free" (credited as Larry Fishburne), in which Hawkeye and B.J. encounter a racist commander who is sending his African-American soldiers into dangerous duty. He also appeared in an episode of Trapper John, M.D. (the year before appearing on M*A*S*H). His Matrix costar, Joe Pantoliano, also appeared both on M*A*S*H and Trapper John, M.D. He appeared in the M*A*S*H episode "Identity Crisis" (also season 10), about a soldier (Pantoliano) who had stolen a fallen friend's identity, as well as his discharge papers, to get out of the fighting.
- Pat Morita, who was famous for his role as Matsuo "Arnold" Takahashi on Happy Days and as Mr. Miyagi in the Karate Kid franchise, played Captain Sam Pak in season two's episode "Deal Me Out" (also with John Ritter) and again in season two's "The Chosen People".
- Shelley Long played in the 1980 episode "Bottle Fatigue", as one of Hawkeye's would-be lady friends. She later played alongside Ted Danson in the hit television comedy Cheers as Diane Chambers.
- George Wendt played in the 1982 episode "Trick or Treatment" as Private La Roche, a Marine treated by Charles Winchester because he had a pool ball stuck in his mouth. He later played alongside Ted Danson and Shelley Long in Cheers.
