"Invasion of the Bane" is the first episode of the British science fiction television series The Sarah Jane Adventures. It was written by series creator Russell T Davies with Gareth Roberts and was directed by Colin Teague. It was originally broadcast on BBC One on 1 January 2007 as a New Year special. Since a full series of the show was commissioned before the script for the episode was written it is not a pilot, despite serving the introductory functions of one.

The Sarah Jane Adventures is a British science fiction television programme that was produced by BBC Cymru Wales for CBBC, created by Russell T Davies, and starring Elisabeth Sladen. The programme is a spin-off of the long-running BBC science fiction programme Doctor Who and is aimed at a younger audience than Doctor Who. It focuses on the adventures of Sarah Jane Smith, an investigative journalist who, as a young woman, had numerous adventures across time and space with the Doctor. Following Sladen's sudden death from cancer, the BBC confirmed that the show would not return for a sixth series.
