Penly is a nuclear power plant on the English Channel coast of the Seine-Maritime department in Normandy, about 10 km northeast of Dieppe. The site straddles the communes of Penly and Saint-Martin-en-Campagne. It has two pressurized water reactor units supplied by Framatome.

Construction began in 1982, and the units were first connected to the grid in May 1990 and February 1992. On 9 June 2004, weakly radioactive water leaked into the sea from a secondary-circuit reserve tank. On 5 April 2012, a small fire in a reactor building caused an automatic shutdown, and nobody was hurt. The next day, a leaking joint released radioactive water into collection tanks, an event rated level 1 on the International Nuclear Event Scale.
