The Clark Stakes is an American Thoroughbred horse race held annually in late November at Churchill Downs in Louisville, Kentucky. Among the oldest races in the United States, it was first run in 1875, the year the racetrack opened for business. Currently a Grade I event, it is open to horses age three and older and is contested on dirt over a distance of 1+1⁄8 miles (9 furlongs). It was known as the Clark Handicap through 2018 before the race conditions were changed to set weights and allowances in 2019. Through 1901, it was restricted to three-year-old horses.
