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 in syndication from May 3 to 6, 2010. The series also got moved to Adult Swim 9 months before Fox canceled the series. The series centers on the Hills, an American family who live in the fictional city of Arlen, Texas, as well as their neighbors, co-workers, relatives, classmates, friends, and acquaintances. 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 was met with 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, Chuck Mangione, Tom Petty, Alan Rickman, Michael Keaton, Johnny Depp, 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.
