Santa Anita Oaks is an American Grade II Thoroughbred horse race held annually in early April at Santa Anita Park in Arcadia, California.
Open to three-year-old fillies willing to race 8.5 furlongs (1+1⁄16 miles) on the dirt.
The race is a Grade II event with a current purse of $200,000 and has been a prep race to the Triple Tiara of Thoroughbred Racing, including the Kentucky Oaks, the Black-Eyed Susan Stakes and Mother Goose Stakes.
Inaugurated in 1935 as a race for two-year-olds, it originated as the Santa Susana Stakes.
In 1986 it was given its current designation as the Santa Anita Oaks.
