The Spinaway Stakes is an American Thoroughbred horse race run annually at Saratoga Race Course in Saratoga Springs, New York. Open to two-year-old fillies, it is a Grade I event contested at a distance of seven furlongs (1,408 metres) on dirt. The Spinaway is part of the Breeders' Cup Challenge series, providing a "Win and You're In" berth for the Breeders' Cup Juvenile Fillies. The race was named for Spinaway who in 1880 was the dominant two-year-old filly in the United States and who beat her male counterparts in every one of her seven stakes wins.
