The Satsuki Shō (皐月賞) is a Grade 1 flat horse race in Japan for three-year-old thoroughbred colts and fillies run over a distance of 2,000 metres (approximately 1+1⁄4 mile) at the Nakayama Racecourse, Funabashi, Chiba, in April.

It was first run in 1939 and is the Japanese equivalent of the English 2,000 Guineas. (Note that the original 2,000 Guineas is run at 1,609 metres, or one mile, about two furlongs shorter than the Satsuki Shō.)

Trial races provide automatic berths to the winning horses or placed horses as specified.
