Langage Power Station is a combined-cycle power plant near the city of Plymouth in Devon, England.

Centrica, the original owners of the site, announced on 16 June 2006 that the natural gas fired power station was to be constructed on their behalf by Alstom. Section 36 consent was granted in 2000 and Reserved Matters were approved in 2005. The 885 MW plant was expected to cost £400 million and to start generating in early 2009, but problems with internal pipework pushed this back. The power station was completed and operations started in March 2010.

Langage was set to be the first fossil fuel power station built in the UK since 2005, but due to delays it was preceded by Marchwood Power Station, which was commissioned in 2009. Multiple other CCGT stations were also commissioned around this time, including Pembroke Power Station and West Burton B. The station was commissioned against an expected 'energy gap' in UK generating capacity, caused by the expected closure of nuclear and older coal-fired stations.
