Taryn Baker is one of the "Newpsies;" wealthy, bored women who live in Newport Beach and spend their days lunching, shopping and gossiping. Many of her appearances centered on her sexually adventurous side. In the first season episode ("The Countdown"), she attended a swingers' party, claiming that such events had "saved [her] marriage." Later, she helped spread the rumour that Luke Ward's father had been having an affair with his male business partner ("The Secret"), and that this was why he had turned her down when she propositioned him. In the fourth season, it was revealed that swinging eventually didn't save her marriage, which ended in divorce. Since her divorce, she had been sleeping with as many young men as possible. She also appeared in flashback, in the fourth season episode ("The Case of the Franks"), where it was revealed that she attended high school with Kirsten Cohen and Jimmy Cooper.
Rachel Hoffman is a former colleague of Sandy Cohen in the District Attorney's office. She invites him to work with her in a private firm called Partridge, Savage and Kahn. Sandy takes the offer, and later Sandy's wife, Kirsten, finds Rachel and Sandy enjoying a drink, causing tension between Sandy and Kirsten. Rachel shares the case of Balboa Heights with Sandy, because the plaintiff is Caleb Nichol's company. While negotiating with Caleb, Caleb accuses Sandy and Rachel of having an affair. Some time afterwards, when Sandy and Rachel work until late in Rachel's apartment, Rachel flirts with Sandy but he rejects her advances. When the chemistry between the two fizzles out, Sandy and Kirsten attempt to set her up with Jimmy Cooper, but fail.
Caleb Nichol, portrayed by Alan Dale, is the widower father of Kirsten Cohen, Hailey Nichol and Lindsay Gardner. He is the owner of The Newport Group, one of the biggest real estate companies in the area, and said to "basically own Newport". His wife Rose, Kirsten and Hailey's mother, died many years ago. Being a lawyer, his son-in-law Sandy becomes suspicious of how Caleb's business is holding up when he receives word of repeated calls from the police and SEC. In the episode "The Way We Were" Caleb is arrested at Sandy and Kirsten's home while they were having dinner and led away by the police in front of everyone, including Seth and Ryan. Sandy, despite his dislike of Caleb, volunteers to represent him as his attorney. He is generally portrayed as dry, sarcastic and calculating businessman who loves his family but shows minimal affection (other than a greeting hug) and sometimes comes across as insincere.
In season 1 he marries Julie Cooper, who had recently divorced her husband Jimmy due to his financial troubles. Her daughters refuse to accept him as their new stepfather and generally ignore him or avoid having any contact with him. He has a love-hate relationship with Kirsten and her family, largely because of his son-in-law Sandy's working-class background. As such, throughout the show, Sandy frequent directs sarcastic remarks at his father-in-law and generally does not hide his distaste for the latter, even in front Kirsten. When Ryan Atwood moves in with the Cohens, Caleb was skeptical as Ryan is from the tough streets of Chino and often insinuated that the teenager was taking advantage of the Cohens' kindness and money. Kirsten would then call him out on it in Ryan's defense, leading to a period of frosty silence between father and daughter. In Season 2, Caleb meets his now-grown illegitimate daughter Lindsay Gardner, who was visiting Newport from Chicago, and again suggests that she was after his money, prompting an angry Kirsten to call him at his office to demand a reconciliation over dinner. However, during the dinner, he suffers a heart attack which was aggravated by his anger at Ryan standing up to his subtle insults. After he hands her divorce papers (which she does not sign), Julie becomes bitter over their marriage as she realizes that she was being treated as a mere band-aid for his deceased wife Rose and tries to kill him but couldn't go through with it. Caleb later dies of a heart attack while swimming in the pool. It is revealed that he was bankrupt and left neither Julie or his daughters anything.
Dr. Kim is the Dean of the Harbor High School. She gives Ryan Atwood a chance to enter Harbor if he passes an admission exam, which he does. She persuades Marissa Cooper to continue her role as social chair despite Marissa's tarnished reputation after overdosing on painkillers. She later returns to have a meeting with Kirsten, Sandy and Ryan, after Ryan reads Oliver Trask's files in the file storage room. In 2005, she was confronted by Julie Cooper and Sandy, claiming that she does not have the power to decide to expel Marissa and Ryan, after the gunshot incident. However, she assists in re-admitting Marissa into Harbor by revealing a precedent in 1996, in which a similar incident to Trey's shooting had occurred with a formerly suspended student. Though never confirmed, it is possible she was replaced by Dean Torres in season 4.
Carson Ward, portrayed by Brian McNamara, is the husband of Meredith Ward, and the father of Eric, Brad, and Luke Ward. He graduated from the University of Southern California with a degree in history. He owns three auto dealerships. Carson and his family appeared happy, but in a sad twist, the family was not really "perfect". At one of his auto dealerships, Luke and Ryan discover Carson making out with another man and after realizing his son caught him, Carson decides to tell his wife who then files for divorce shortly after. Months later, Carson and Meredith's divorce has been finalized and Carson moves to Portland with Luke moving with him, but Brad and Eric staying behind in Newport with their mother. Carson later returns in the season 2 episode "The Distance", where Seth was staying at Luke and Carson's house in Portland.

D.J. played by Nicholas Gonzalez is described by creator Josh Schwartz as "the yard guy who works at Caleb's mansion". Later, however, it is revealed that Marissa Cooper has struck up a relationship with him after Ryan Atwood left Orange County. Marissa and DJ kept their trysts secret to prevent Marissa's mother Julie from finding out and firing D.J. When Ryan returns to Newport and asks Marissa if she was seeing anyone, Marissa lies to him and says she's single. However, Ryan discovers the truth when he finds Marissa and D.J. kissing. D.J. is angry with Marissa when he finds out about her lie, saying he felt like a back-up she only came to when Ryan was not around. Marissa apologizes and the two reconcile shortly afterward, with Marissa revealing their relationship to her mother by announcing that as he was her boyfriend, D.J. should appear with them in family portrait photographs to be taken with Caleb Nichol. As expected, this enrages Julie, who felt D.J. was socially beneath her daughter. Arranging a secret meeting with him, Julie gives D.J. a check for $5,000 to leave Marissa. D.J. does so, but first gives the check to Marissa, suggesting she goes on a spending spree. He then leaves her, saying he had no regrets about their relationship, but he feels Marissa was with him less because she liked him, and more because she hated Julie.
Renee Wheeler once had an affair with Caleb Nichol which led to her having a child, Lindsay Gardner. Caleb continues to pay her money and the DA misunderstand that, thinking that Caleb is bribing Renee for a building permit, for which Caleb is arrested ("The New Era"). Sandy figures out that the reason Caleb pays Renee is that she is the mother of his illegitimate child ("The SnO.C."). Caleb admits to having had an affair so he will be released from prison but the news angers his daughter, Kirsten Cohen ("The Chrismukkah That Almost Wasn't"). Renee later returns, asking Ryan Atwood to help her stop Caleb from adopting Lindsay as Caleb wants a paternity test and Renee isn't sure if Caleb really is Lindsay's father ("The Test"). The test results confirm Caleb's paternity but Lindsay ultimately decides that she doesn't want Caleb to adopt her because of how he treats her and she and her mother leave Newport for Chicago ("The Rainy Day Women").
Rebecca Bloom is an ex-girlfriend of Sandy Cohen, who is described as Sandy's "love of [his] life" by Kirsten Cohen. Twenty years ago, she was accused of burning down a lab and killing a man in the fire. Rebecca denies that and claims that she fled the site because she did not want to testify against her friends. Her father, Max, asks his former student Sandy to find Rebecca, as he is dying and wants to see his only daughter one last time before passing away. Rebecca shows up, and Max asks Sandy to clear her name; soon after this, he dies. Sandy continues to assist Rebecca, thus placing his marriage in jeopardy. Sandy and Rebecca finally realize that their love was a thing of the past, and Rebecca flees yet again.

Lance Baldwin is Julie Cooper's ex-boyfriend. Back in the 1980s, when she was in desperate need of money, she starred in a porn flick he directed, entitled "The Porn Identity".

In July 2005 it was reported that Jeri Ryan was joining The O.C. in a seven-episode arc as "a mysterious woman Kirsten Cohen (Kelly Rowan) befriends in rehab". Later on Josh Schwartz said that "We were told to add this Jeri Ryan character to the show that we had no idea what to do with. We were just told we had to add an adult female character. It went nowhere, and we had no plan for it, and it just didn’t fit the show." Rob Lineberger of DVD Verdict "thought Jeri Ryan made a compelling bad girl". Derek Hanson said that Ryan's addition was meant to get the "14–24 demographic excited", but stated that Charlotte Morgan had "a terrible storyline, that just didn't sit quite right."

According to Kirsten, Frank was an abusive alcoholic, hence Ryan's reluctance to rekindle the relationship. Frank is invited to dinner at the Cohen's. However the night ends with Sandy punching Frank in the face after a confrontation over a lie Frank told about dying of cancer in order to get Ryan to meet with him.
