The Chinon Nuclear Power Plant (French: Centrale nucléaire de Chinon) is near the town of Avoine in the French Indre et Loire département, on the Loire river (approximately 10km from the town of Chinon). The power station has seven reactors, of which three are now closed.

The nuclear power station employs approximately 1,350 full time workers. The operator is the French company Électricité de France (EDF).

The site housed three of the first generation of French plants of a Magnox-type (UNGG) design. Since then, four of the first French PWR series have been built. The site uses four cooling towers that were built with a low profile for the specific purpose of not blocking the views of the Loire.

The Chinon Nuclear Power Plant is on the large side for a French plant. It feeds approximately 6% of the national electricity demand of France.
