The Prix Morny is a Group 1 flat horse race in France open to two-year-old thoroughbred colts and fillies.
It is run at Deauville over a distance of 1,200 metres (about 6 furlongs), and it is scheduled to take place each year in August.
The event is named in memory of Auguste de Morny (1811–1865), the founder of Deauville Racecourse.
Its usual venue was closed during World War II, so it was held temporarily at Longchamp (1941–42, 1944) and Maisons-Laffitte (1943, 1945).
The event opened to foreign horses in 1947, and that year's race was won by a British colt named Delirium.
