Atlantis is a British fantasy-adventure television programme inspired by Greek mythology and created by Johnny Capps and Julian Murphy with Howard Overman. It premiered on 28 September 2013 on BBC One. In the show, submarine pilot Jason washes up on the shores of legendary Atlantis and must navigate the powerful leaders of the mythological realm.

Atlantis was the biggest new Saturday night drama series launch across all BBC channels since 2006, even up on the launch of hit show Merlin. It also managed to draw 1 million viewers away from the highly popular ITV show The X Factor, which aired at the same time in the UK.

On 26 October 2013, BBC One ordered a second series of the show, which began airing on 15 November 2014. On 23 January 2015, it was announced that the series had been cancelled.
