BBC South West is the BBC English Region serving Devon, Cornwall and the Channel Islands.

BBC South West's television service (broadcast on BBC One South West) consists of the flagship regional news service Spotlight, the opt-out service BBC Channel Islands, the topical magazine programme Inside Out and a 20-minute opt-out during Sunday Politics. A late night football magazine show Late Kick Off is co-produced with BBC South, BBC West and the independent production company Pergall Media.

The region is the controlling centre for BBC Radio Devon, BBC Radio Cornwall, BBC Radio Jersey and BBC Radio Guernsey.

On weekdays, the four stations carry local programming between 5am and 6pm before joining together for networked programming between 6pm and closedown at 1am. Weekend evening programmes are also simulcast with stations in the BBC West region.

BBC South West also produces regional news & local radio pages for BBC Red Button and BBC Local websites for each county.

BBC South West began a regional television service on 20 April 1961 (nine days before the first broadcast of the rival ITV station, Westward Television) with ten-minute news bulletins on weekdays, originally presented by Tom Salmon. A year later, the bulletin was expanded and relaunched as the news magazine programme South West at Six (hosted by Sheila Tracy) before being renamed again on 30 September 1963 as Spotlight South West.
