Mission Hill is an American adult animated sitcom created by Bill Oakley and Josh Weinstein for The WB. It originally aired for five episodes from September 21, 1999 to July 16, 2000; unaired episodes were burnt off on Cartoon Network's Adult Swim from May 26 to August 11, 2002. The series follows Andy French, a retail worker who lives with roommates Jim and Posey as well as their dog, Stogie. Andy's lifestyle is taken for a turn when his younger brother Kevin moves in with him.

While initially garnering poor ratings, it has since gained a cult following, and is also popular outside of the United States and Canada, receiving broadcasts in Australia, Eastern Europe, Latin America, Spain and New Zealand. Stylistically, the series is recognizable for its bright, neon color palette, and features a peculiar mixture of modern animation and traditional "cartoonish" drawings (dashed lines coming from eyes to indicate line of vision, red bolts of lightning around a spot in pain). The style was made to be reminiscent of 1930s rubber hose cartoons like Fleischer Studios, Walt Disney, Warner Bros., and MGM, as well as mid-century modern cartoons with the likes of Hanna-Barbera, UPA, Jay Ward, and The Pink Panther. The designs were done by Lauren MacMullan, who cites the comic series Eightball as her source of inspiration for her overall design.
