Off the Air is an American psychedelic anthology television series created by Dave Hughes for Adult Swim. The series is presented without explanation or narration as a showcase of surreal footage arranged around a single loose theme (expressed in the episode title) and blended without pause into a single continuous presentation. The series premiered on Adult Swim on January 1, 2011, 4:00 am New Year's Day.

Hughes is a former employee of MTV Animation who first pitched it to Mike Lazzo at Adult Swim after producing a video mixtape for the network's 2010 Carnival Tour event. As a result of its 4 a.m. graveyard slot and small selection of episodes, the series remains relatively unknown on the network, but has been received positively and dubbed a cult phenomenon by critics and Adult Swim itself.

The series has aired 50 episodes and 3 specials over the course of 13 seasons, including two episodes, "Technology" (by Wham City) and "Paradise" (by Ghosting.tv), that Adult Swim announced on October 13, 2017, would air in late 2017. On December 31, 2019, Dave Hughes tweeted that the episode "Patterns" was the "last [one] for now", indicating that the series had been put on hiatus until further notice. Following this, the show received four more seasons: season 10 on June 9, 2020; season 11 on October 12, 2021; season 12 on July 4, 2022; and season 13 on December 19, 2023.
