The San Antonio Stakes is an American Thoroughbred horse race held at Santa Anita Park in Arcadia, California. Raced on the dirt, it is for horses age three and older. In 2017, the distance was shortened from 1+1⁄8 miles to 1+1⁄16 miles. The race was originally run under handicap conditions but is now run under allowance weight conditions, with specified weight reductions for horses who meet certain conditions. The San Antonio has been a Grade II event since 1990. The current purse is $200,000. Inaugurated in 1935, the San Antonio Handicap was run at a mile and a sixteenth in 1940 and 1941.
