The Prix Foy is a Group 2 flat horse race in France open to thoroughbred colts and fillies aged four years or older.
The event is named in memory of Henri Foy (1872–1954), a long-serving member of the Société d'Encouragement, a former governing body of horse racing in France.
The race was initially contested over 2,300 metres, and for a period it was open to horses aged three or older.
The present system of race grading was introduced in 1971, and the Prix Foy was given Group 3 status.
It was subsequently run on the same day as the Prix Niel, a similar event restricted to three-year-olds.
