The Prix d'Aumale is a Group 3 flat horse race in France open to two-year-old thoroughbred fillies.
It is run at Chantilly over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in September.
The present event is named after Henri d'Orléans (1822–1897), who inherited the title Duc d'Aumale.
Upon his death the Duc bequeathed his Chantilly estate, including the racecourse and the château, to the Institut de France.
Since the 1970s, the venue of the Prix d'Aumale has been switched between Chantilly (1973–82, 1997–2001, 2004–09, 2012–17) and Longchamp (1983–96, 2002–03, 2010–11, 2018–2020).
