Pac-Man title screen featuring the ghosts and their names. Below is their appearance when they are edible.
|First appearance||Pac-Man (1980)|

Blinky, Pinky, Inky and Clyde are the primary group of fictional ghosts (Japanese: モンスター monsutā, "monsters") who serve as the main antagonists in the Pac-Man franchise. Several different ghosts have appeared throughout the franchise, aside from the ones in the main aforementioned group.
The enemies in Pac-Man are known variously as "ghosts", "goblins", and "monsters". Despite the seemingly random nature of the enemies, their movements are strictly deterministic, which players have used to their advantage. In an interview, creator Toru Iwatani stated that he had designed each enemy with its own distinct personality in order to keep the game from becoming impossibly difficult or boring to play. More recently, Iwatani described the enemy behaviors in more detail at the 2011 Game Developers Conference. He stated that the red enemy chases Pac-Man, and the pink and blue enemies try to position themselves in front of Pac-Man's mouth. Although he claimed that the orange enemy's behavior is random, the game's code reveals that it actually chases Pac-Man most of the time, but also moves toward the lower-left corner of the maze when it gets too close to Pac-Man.
In the Pac-Man cartoon, with the male Ghost Monsters wearing various styles of hats and partnered with a new ghost named Sue (who was purple and wore earrings), the Ghost Monsters work for Mezmaron who assigns them the job of finding the Power Pellet Forest. Just as Pac-Man could "chomp" the Ghost Monsters to devour their "suits" after gulping down a power pellet and thus turning the Ghost Monsters blue — with their disembodied "eyes" floating back to Mezmaron's lair — the Ghost Monsters themselves, whenever Pac-Man hadn't been able to consume a power pellet for a time, could likewise "chomp" Pac-Man to defeat him. The episodes "Chomp-Out at the O.K. Corral" and "The Greatest Show in Pacland" featured the Ghost Monsters' 3-year-old cousin named Dinky who was bratty, which greatly annoyed all the male ghost monsters.
In the 2013 TV series Pac-Man and the Ghostly Adventures, the four Ghosts come from the Netherworld. Though they are ruled by Lord Betrayus, they are actually good-natured spirits and often supply Pac-Man with information about Lord Betrayus' plots, while ensuring Betrayus doesn't catch them in the act. It is also suggested that they could be reunited with their bodies and brought back to life, though their 'living' forms are unknown. There were also some Ghosts that were exclusive to the TV series like Cyclops Ghosts (a race of heavyset, horned Ghosts with one eye), Fire Ghosts (a race of orange Ghosts who can emit fire from their body), Tentacle Ghosts (a race of 4-eyed purple-black Ghosts who look similar to jellyfish), Guardian Ghosts (a race of large Ghosts who guard the Netherworld), and Aqua Ghosts (a race of light blue Ghosts with fins on their head).
Below is the description of each Ghost.

Blinky, whose original name is listed as Shadow, is a red ghost who, in the original arcade game, follows behind Pac-Man. He is considered the leader of the ghosts. In the Pac-Man cartoon, Blinky (voiced by Chuck McCann) is slow-witted and cowardly with grammar problems. In Pac-Man and the Ghostly Adventures, Blinky (voiced by Ian James Corlett in the TV series and by Lucien Dodge in the video game) is the default leader of the Ghost Gang Family and tends to help the winning side. Blinky receives a speed boost after a number of pac-pellets have been cleared. This mode has been informally referred to as "Cruise Elroy". 
Pinky, whose original name is listed as Speedy, is a pink ghost who, in the original arcade game, positions itself in front of Pac-Man. In the Pac-Man cartoon, Pinky (voiced by Chuck McCann) is depicted as a male dimwitted shape shifter. In recent games, and Pac-Man and the Ghostly Adventures, Pinky (voiced by Ashleigh Ball in the TV series and by Julia Kliewer in the video game and sequel) is depicted as a female with a crush on Pac-Man, which often puts her at odds with Cylindria.
Inky, whose original name is listed as Bashful, is a cyan ghost who, in the original arcade game, has a fickle mood. He can be unpredictable. Sometimes he chases Pac-Man aggressively like Blinky; other times he jumps ahead of Pac-Man as Pinky would. He might even wander off like Clyde on occasion. In the Pac-Man cartoon, Inky (voiced by Barry Gordon) is depicted as dim and loony. In Pac-Man and the Ghostly Adventures, Inky (voiced by Lee Tockar in the TV series and by Bryce Papenbrook in the video game) is the youngest member. Though the smartest, he lacks focus most of the time. In Pac-Man, Inky likes to appear in front of Pac-Man's face.
Clyde, whose original name is listed as Pokey, is an orange ghost who, in the original arcade game, acts stupid. He will chase after Pac-Man in Blinky's manner, but will wander off to his home corner when he gets too close. In Ms. Pac-Man, this ghost is named Sue, and in Jr. Pac-Man, this ghost is named Tim. In the animated series, Clyde (voiced by Neil Ross) is the leader of the group. In recent games and Pac-Man and the Ghostly Adventures, Clyde (voiced by Brian Drummond in the TV series and by Orion Acaba in the video game) is depicted as a large ghost who is simple, but not unintelligent and has an appetite equal to Pac-Man's. He lacks the devious natures of his brothers and sister and is considerate towards others.

With the release of further Pac-Man games, more ghosts have been added.
- Kinky – the golden yellow Ghost who appeared only in Pac-Man Arrangement. Also called Kinzo, Kinky is the scientist of the Ghosts who has the ability to combine with other Ghosts. When he combines with Clyde (note: in Pac-Man Arrangement, Clyde was red and Blinky was orange), Kinky becomes a bull-like ghost named Urchin, who can charge after Pac-Man. When he combines with Inky, Kinky's glasses appear on Inky's body and grant this new combined ghost (named Stylist) the ability to split in two. Stylist's reflection will mirror his movements on the other half of the map (about the vertical axis). When Kinky combines with Pinky, the resulting ghost is rabbit-like and named Romp. Romp can hop to any part of the map, usually very close to Pac-Man's position. The combination of Kinky and Blinky results in Crybaby, a bigger and chubbier version of Blinky who adds 20-point Pac-Dots anywhere in the maze.
- Orson / Toc-Man – a greenish-gray intellectual Ghost who initially appears as the main antagonist of Pac-Man World under the alias of Toc-Man the robot, mocking Pac-Man. In Pac-Man World 3, Orson has reformed and is now an ally of Pac-Man.
- Spooky – a dark gray Ghost in gray armor who is the King of the Ghosts in ancient times until he was sealed under the Golden Fruit Tree in Pac Village by Sir Pac-A-Lot. Spooky is the main antagonist of Pac-Man World 2.
- Ghost Witch of Netor - the leader of the ghost gang and the main antagonist of Pac-Man 2:The New Adventures and Pac-in-Time.
- Funky – a jumping green Ghost who debuted in the game Pac-Mania. He has an interest in Sue and jumps lower than Pac-Man. Funky and Spunky only jump in the worlds of Sandbox Land and Jungly Steps.
- Spunky – a jumping dark gray Ghost who debuted in Pac-Mania. He is the male like Funky who jumps just as high as Pac-Man. He was recolored black in some home console remakes/ports. He has recently been depicted in games as a "sleeping ghost".
- Sue – the female counterpart of Clyde in Ms. Pac-Man, entirely identical to him. In the Hanna-Barbera Pac-Man animated series, Sue (voiced by Susan Silo) is featured as Clyde's second-in-command and is recolored purple. She also appears in Pac-Land and Pac-Mania, still purple and wearing mascara and eyeshadow, greatly resembling her cartoon counterpart.
- Tim – an orange ghost who appeared exclusively as Clyde's replacement in Jr. Pac-Man.
- Yum-Yum – the female red Ghost who debuted in Jr. Pac-Man. She is a relative of Blinky and has a romantic relationship with Jr. Pac-Man. Yum-Yum appears exclusively in Jr. Pac-Man's cutscenes.
- Wandy – a white Ghost and wizard who appeared as the antagonist of Pac-Man All-Stars. He kidnaps the fairies of Pac-Land to prevent them from creating more power pellets.
- Lord Betrayus (full name: Betrayus Sneakerus Spheros) – a black and white ghost who is once a general of an army in Pac-World and the brother of President Spheros in the Pac-Man TV series. Soon later after he died, he became the supreme ruler of the Netherworld and of all Ghosts and Monsters. He acts as the main antagonist of Pac-Man and the Ghostly Adventures and its video game adaptions. His primary goal is to steal the Power Berries and take over Pac-World to rule it with an iron fist. He is currently voiced by Samuel Vincent.
- Butt-ler – Betrayus' long suffering personal servant and butler who appears in Pac-Man and the Ghostly Adventures. He is a purplish-gray ghost with a butt-shaped head, topped with a dapper black hat. He's always loyal to his master. He will take some small satisfaction seeing Betrayus fall flat on his face.
- Dr. Buttocks – the Netherworld's greatest mad scientist and Butt-ler's twin brother who also has a butt-shaped head, but is light blue, has a cybernetic right hand, wears glasses and speaks with a German accent. Sometimes, he doesn't like Butt-ler. Dr. Buttocks specializes in monster experimentation in hopes of achieving Pac-World domination. He sometimes suspects that the Ghost Gang are working with Pac-Man, but has had no luck convincing Betrayus of this since he usually blames him or his brother for his failures and sometimes tortures him for fun. He wants all of the workers to get out of his way.
