The Prix des Réservoirs is a Group 3 flat horse race in France open to two-year-old thoroughbred fillies.
It is run at Deauville over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in October.
Its title refers to four large reservoirs used for watering Chantilly's racetrack.
It was initially open to two-year-olds of either gender and contested over 1,400 metres.
Due to World War II, the event was cancelled in 1939 and 1940.
