Île-Tudy (French pronunciation: [il tydi]; Breton: Enez-Tudi) is a commune in the Finistère department of Brittany in northwestern France.

Inhabitants of Île-Tudy are called in French Îliens.

The United States Navy established a naval air station on 14 March 1918 to operate seaplanes during World War I.

The base closed shortly after the First Armistice at Compiègne.
