Sit Down, Shut Up (sometimes also known as Sit Down, Shut Up! in some promos) is an American adult animated television series developed by Mitchell Hurwitz for the Fox Broadcasting Company. The series focuses on a group of high school teachers in a small town in Florida "who don't care about teaching". The series premiered on April 19, 2009, in the Animation Domination block on Fox, but after four episodes aired, Fox removed the show from the block due to low ratings. The remaining nine episodes aired on Saturdays at midnight from later in the year. The show was cancelled on November 21, 2009.

Based on the Australian live-action sitcom of the same name, creator Mitchell Hurwitz came up with the idea for an animated version in 2000. He wrote a script for a pilot episode, but "kept it in a drawer" until he pitched the show to different networks in 2008 when he needed money. Hurwitz said that "it was just a wacky show, and nobody wanted it", but eventually Fox picked it up as a primetime animated series.

Sit Down, Shut Up met with mixed reviews from critics. Orlando Sentinel called the series a "disaster", and Newsday called it "raw, vulgar and blithely offensive, with so many triple and quadruple entendres for so many sexual acts". The Hollywood Reporter criticized the series' use of fourth wall breaks, and said that it was "painful to watch how hard the show tries to be funny". IGN gave it a more positive review, saying "it should continue to be a very entertaining show", and TV Squad said that it "definitely grows on you". It was nominated an Artios Award for its casting in 2009.
