Red Dwarf is a British comedy franchise which primarily comprises twelve series and a feature-length special of a television science fiction sitcom that aired on BBC Two between 1988 and 1993 and from 1997 to 1999, and on Dave in 2009 and 2012 and from 2016 to the present, gaining a cult following. The series was created by Rob Grant and Doug Naylor.

The first six series were written by Grant and Naylor, while Series VII and VIII were written by Naylor with collaborations from other writers, and Series IX to XII and the 2020 special The Promised Land were written by Naylor alone. Series I and II were produced by Paul Jackson Productions (with Grant Naylor Productions taking over from Series III) for BBC North, and broadcast on BBC2. Red Dwarf first aired on 15 February 1988 and ended its original run on BBC2, by then rebranded BBC Two, on 5 April 1999 after eight series, with some PBS stations in the United States airing the entire eighth series earlier on 7 March. From 2009, Grant Naylor Productions produced new episodes for UKTV, which were broadcast on the TV channel Dave.

The series follows the fortunes of Dave Lister who is stranded three million years in the future, together with the hologrammatic representation of his former bunkmate and immediate superior Arnold Rimmer; a creature known only as Cat; and the ship's computer Holly. During Series II, the crew encounter a mechanoid called Kryten, who joins them from Series III onwards. In Series VI the Red Dwarf ship has been stolen from the crew, forcing them to travel in the smaller Starbug craft for two series. In Series VII Kristine Kochanski, Lister's former love interest, joins the crew, following the departure of Rimmer. In series VIII the entire crew of the Red Dwarf ship—including a pre-accident Rimmer—are resurrected, but the Starbug crew, along with Rimmer, find themselves sentenced to two years in the ship's brig for "abusing classified information". Series IX (Red Dwarf: Back to Earth) involves Lister, Rimmer (back as a hologram), Cat, and Kryten hallucinating that they've arrived on Earth in another dimension in the early 21st century, and Series X to XII sees the same four crew members continue their adventures back on Red Dwarf, Kochanski having departed due to Lister's descent into depression and Holly offline due to water damage. A back-up of Holly is installed in The Promised Land.

As of 9 April 2020, 74 episodes of Red Dwarf have aired, including one special, concluding the twelfth series.
