The Old Hat Stakes is an American flat Thoroughbred horse race for three-year-old fillies held annually at Gulfstream Park in Hallandale Beach, Florida. It is currently a Grade III race run over a distance of 6 furlongs on dirt. It became a graded race for the first time in 2005.
The race was named after Old Hat, an exceptional racing mare who often vied with the great Affectionately. Old Hat raced for six years and won the American Champion Older Female Horse award in 1964 and 1965. Old Hat started 80 times, winning 35, placing in 18, and showing in 9. The Old Hat is an important prep race for the Kentucky Oaks.
