The Diana Stakes is an American Thoroughbred horse race. Named for the mythological goddess Diana, the race is run each year at Saratoga Race Course in Saratoga Springs, New York. Inaugurated in 1939, it is open to fillies and mares age three and up willing to race the one and one-eighth miles on the turf. The race is a Grade I with a current purse of $500,000. It became a Grade I race in 2003.

From inception in 1939 to 1973, the race was run on Saratoga Race Course's dirt track. Because of large fields, it was split into two divisions in 1973, 1982, and 1983. The race was run at Belmont Park from 1943 to 1945 due to travel restrictions during World War II.
