The Las Flores Stakes is an American Thoroughbred horse race held annually during the first week of April at Santa Anita Park in Arcadia, California.
In 2015, due to the 2013 closing of Hollywood Park Racetrack and extensive rescheduling, the race was run in early March.
Open to fillies and mares age four and older, the Grade III event is contested on Pro-Ride synthetic dirt over a distance of six and one half furlongs.
Inaugurated in 1951 as the Las Flores Handicap the event was run for three-year-olds and up from 1951 through 1959, for four-year-olds and up from January 1960, 1972, 1975, 1981 through 1987, and again in 1989, and for all ages December 1972, 1973 and 1979.
The Las Flores Handicap was run in two divisions in 1963.
