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.

BBC Cymru Wales is a division of the BBC and the main public broadcaster in Wales.
