The event was established in 1919, and it was originally called the Prix de la Plage Fleurie. It was named after the
Plage Fleurie, the stretch of coastline where Deauville is located. The inaugural running was contested over 1,600 metres, but the distance was extended to 2,000 metres in 1920. It reverted to its original length the following year. The race was renamed in memory of the Comte de Quincey (died 1924), a member of the Société d'Encouragement, in 1925. As the chief steward of this organisation, Quincey had instigated such decisions as the merger with the Société des Courses de Deauville and the creation of the
Prix de l'Arc de Triomphe. The Prix Quincey was cancelled twice during World War II, in 1940 and 1944. For the remainder of this period, while its regular venue was closed, the race was switched between
Longchamp (1941–42, 1945) and
Maisons-Laffitte (1943). The race was originally open to three-year-olds. It was restricted to horses aged four or older from the 2018 running. ==Records==
