Mad TV (stylized as MADtv) is an American sketch comedy television series created by David Salzman, Fax Bahr, and Adam Small. It premiered on October 14, 1995, on Fox, where it ran for 14 seasons, with its final, 326th episode airing on May 16, 2009. Loosely based on the humor magazine Mad, Mad TV's pre-taped satirical sketches were primarily based around pop culture–featuring parodies of films, TV series, music videos, celebrities, and occasionally politics–and original characters, many of which were recurring.

Salzman created Mad TV after he and record producer Quincy Jones purchased the rights to Mad in 1995, and he soon brought on former In Living Color writers Bahr and Small as showrunners. The show was intended to compete with fellow sketch comedy series Saturday Night Live, which was being ridiculed by critics and audiences upon Mad TV's premiere. Mad TV typically fell behind SNL in ratings and has since been described by critics as an edgier "cousin" of SNL. Fox also made few efforts to promote the series and often made budget cuts to it; its eventual cancellation in 2009 was due to budgetary concerns.

The show's diverse cast over the years consisted of popular members such as its longest-running original member, Debra Wilson, and its longest-running member overall, Michael McDonald. Recurring celebrity impressions and characters attracted both fan followings and controversy, while critical reception of the series varied, though it was often negative. It has appeared on several critics' lists of the best sketch comedy television series of all time and was nominated for a number of awards, including 43 Primetime Emmy Awards, five of which it won.

After a 20th anniversary reunion special aired on The CW on January 12, 2016, the show's eight-episode 15th season was produced and broadcast on the same network, premiering on July 26, 2016.
