James "Jim" Gordon is a fictional character adapted for television by screenwriter Bruno Heller. He serves as the main protagonist of the Warner Bros. and DC Comics television series Gotham, portrayed by Ben McKenzie.

He is based on a character of the same name created by Bill Finger and Bob Kane, debuting in Detective Comics #27 (May 1939), though is most well-known as the supporting lead of the superhero comic, Batman.

McKenzie received a generally positive critical reception for his portrayal of the character, appearing in every episode of the series, and the novel Gotham: City of Monsters, set in-between the events of the second and third seasons.

Gordon is introduced as a homicide detective and Iraq War veteran of the U.S. Army who has recently been transferred to Gotham City, where he lives with his fiancée, Barbara Kean. In his first case, Gordon and his partner, Detective Harvey Bullock, are assigned to investigate Thomas and Martha Wayne's murder. After arriving at the crime scene, he comforts the Waynes' son, Bruce, who witnessed his parents' murder, promising him that he would do everything in his power to find the murderer and bring them to justice.

During his investigation, Gordon runs afoul of a gangster Fish Mooney, who takes him hostage. Bullock later goes searching for him and is captured alongside him. The two are freed by Gotham's most powerful mob boss, Carmine Falcone, who was an old friend of Gordon's deceased father. In return, Falcone asks Gordon to kill Oswald "Penguin" Cobblepot, Mooney's underling who had informed her of the GCPD. Instead of killing him, Gordon fakes Cobblepot's death and orders him never to come back to Gotham.

After Gordon's gun is used to kill Dick Lovecraft, a corrupt billionaire, Mayor Aubrey James reassigns him to Arkham Asylum as a guard. Gordon is later reinstated as a homicide detective by Commissioner Gillian B. Loeb after he captures a serial killer who had escaped from Arkham during a prison riot. Gordon then blackmails Loeb into naming him the President of the Gotham City Police Union. At the end of the season, he discovers that Barbara is in fact a murderer, and begins a relationship with Arkham physician Leslie "Lee" Thompkins. He is also present during a gang war between Mooney and mob boss Sal Maroni, during which Mooney and Maroni are killed, Falcone retires, and Cobblepot takes control of Gotham's criminal underworld.

After the events of the first season, Gordon is demoted to patrol officer by a vengeful Loeb. He is later reinstated as a Detective after Cobblepot blackmails Loeb into retiring and appointing Captain Sarah Essen to replace him as Commissioner.

Theo Galavan and his sister Tabitha launch a campaign of terror against Gotham in the name of the Order of St. Dumas. This leads to the kidnapping of Mayor Aubrey James and the death of Commissioner Essen. Gordon becomes determined to arrest the perpetrators. Meanwhile, Theo and Tabitha recruit Barbara and Jerome Valeska to their cause. Gordon's relationship with Lee begins to deteriorate due to his obsession with catching the Galavans and Barbara.
