The Sky at Night is a documentary television programme on astronomy produced by the BBC. The show had the same permanent presenter, Sir Patrick Moore, from its first monthly broadcast on 24 April 1957 until 7 January 2013. The latter date was a posthumous broadcast, following Moore's death on 9 December 2012. This made it the longest-running programme with the same presenter in television history. Many early episodes are missing, either because the tapes were wiped or thrown out, or because the episode was broadcast live and never recorded in the first place.

Sir Patrick Alfred Caldwell-Moore was an English amateur astronomer who attained prominence in that field as a writer, researcher, radio commentator and television presenter. He was also a minor politician.
