Dungeness nuclear power station comprises a pair of nuclear power stations located on the Dungeness headland in the south east of Kent, England.

Dungeness A houses two Magnox reactors of 219MW each, which have been shut down permanently in December 2006. An intermediate level waste store is planned on the site of the turbine hall for 2014. The waste store and reactor building will then be placed on a care and maintenance basis until 2103, with final site clearance and closure by 2111. Decommissioning is estimated to cost £1.2 billion.

Dungeness B is the site of two advanced gas-cooled reactors (AGR) of 615MW each, which began operations in 1983 and 1985 respectively. Dungeness B was the first commercial scale AGR power station to be constructed.

On 15 April 2009 Dungeness was included in a list of 11 potential sites for new nuclear power stations, at the request of EDF Energy, which owns and operates Dungeness B. The government did not include Dungeness C in its draft National Policy Statement published on 9 November 2009, citing environmental reasons and concerns about coastal erosion and associated flood risk. The site was ruled out by Secretary of State for Energy and Climate Change Chris Huhne in October 2010 with the former government's list of eleven potential sites reduced to eight.
