Crozon (French pronunciation: [kʁɔzɔ̃], [kʁozɔ̃]; Breton: Kraozon, [ˈkrɔːzõn], locally [ˈkraõn]) is a commune in the department of Finistère and the administrative region of Brittany, northwestern France.

It is bordered by the communes of Camaret-sur-Mer to the west, Roscanvel to the northwest, Lanvéoc to the north, Landévennec to the north-east and Telgruc-sur-Mer to the east.

Crozon harbours Île Longue, the base of the French strategic nuclear submarines.

In common with many other French towns, Crozon has a number of fêtes and festivals at various times of year.

In 2008, 4.58% of primary-school children attended bilingual schools, where Breton language is taught alongside French.
