King of the Hill is an American animated sitcom created by Mike Judge and Greg Daniels that initially aired on Fox from January 12, 1997 to September 13, 2009, with four more episodes airing syndicated from May 3 to 6, 2010. The series centers on the Hills, an American family in the fictional city of Arlen, Texas, as well as their neighbors, co-workers, relatives, classmates, friends, and acquaintances. Series protagonist, patriarch, and everyman Hank Hill works as assistant manager at Strickland Propane. He lives in a ranch-style house with his wife Peggy, his son Bobby, his niece Luanne, and his pet bloodhound Ladybird. Hank's neighbors are his longtime friends Bill Dauterive, a divorced, bald, overweight military barber and former high school football star; Dale Gribble, a paranoid, pro-gun, anti-government pest exterminator; and Jeff Boomhauer, a charismatic, soft-spoken, often unintelligible bachelor whose occupation is revealed in the final episode of the series. The show's realistic approach seeks humor in the conventional and mundane aspects of everyday life, such as blue-collar workers, substitute teachers, and the trials of puberty.

Judge began creating King of the Hill during his time making the MTV series Beavis and Butt-Head, which he also created and voiced in. After pitching the pilot to Fox, Judge was paired with Greg Daniels, an experienced writer who previously worked on The Simpsons. The series debuted on the Fox network as a mid-season replacement in 1997, quickly becoming a success. The series' popularity led to worldwide syndication, and cable reruns currently air on FXX and Adult Swim, having aired on FX and Comedy Central in the past. The show became one of Fox's longest-running series, with a total of 259 episodes over the course of its 13 seasons. Four episodes from the final season were planned to air on Fox, but later premiered in nightly syndication in May 2010.

King of the Hill received universal acclaim and has since garnered a strong cult following. It was named by Time magazine in its 2007 list of "The 100 Greatest TV Shows of All Time". The series has won two Emmy Awards and has been nominated for seven. Its celebrity guest stars include Texas Governor Ann Richards (playing herself), Chuck Mangione (playing a fictionalized version of himself), Tom Petty (playing the recurring character Lucky), Alan Rickman (playing a king at a Renaissance fair), Michael Keaton (playing a crazy pork millionaire), and numerous country music artists. On January 18, 2022, Judge and Daniels announced the forming of a new company called Bandera Entertainment, with a revival of King of the Hill being one of several series in development. On January 31, 2023, it was announced that Hulu picked up the revival.
