Colstar (foaled 1996 in Kentucky) is an American Thoroughbred racehorse and broodmare. Sired by the 1991 Breeders' Cup Mile winner, Opening Verse, she was out of the mare Ascend, a daughter of Preakness and Belmont Stakes winner, Risen Star.
Racing in Maryland, Colstar's first important win came in 1999, in the Grade III Martha Washington Stakes, following by a win the next year in the Gallorette Handicap. Her other racing successes includes back-to-back wins in the Locust Grove Handicap at Churchill Downs and the Grade I Flower Bowl Invitational Stakes at Belmont Park.
Retired to broodmare duty, Colstar has produced four unraced offspring to date.
