The Oak Leaf Stakes is an American Thoroughbred horse race held annually at the end of September at Santa Anita Park in Arcadia, California. It is restricted to two-year-old fillies. The Grade I race is contested at a distance of one and one-sixteenth miles on the Pro-Ride synthetic dirt track at Santa Anita Park's Oak Tree Meeting.
The race is currently part of the Breeders' Cup Challenge series. The winner will automatically qualify for the Breeders' Cup Juvenile Fillies.
From 1997 through 2001, the Oak Leaf Stakes was raced at a distance of one mile (8 furlongs).
