The Martha Washington Stakes is an American Thoroughbred horse race held annually at Oaklawn Park Race Track in Hot Springs, Arkansas.
Open to three-year-old fillies, it is contested on dirt over a distance of 1 1/16 mile.
It is now run in late January as an early prep race in the Road to the Kentucky Oaks.
Inaugurated in 1979, it was raced at 6 furlongs (3⁄4 mile) until 2003 when it was modified to its present distance.
The Martha Washington Stakes was run in two divisions in 1979 and 2008.
