Kostroma (foaled 1986 in Ireland) was an Irish-bred Thoroughbred racehorse who competed successfully in Ireland as well as in the United States, where she set a world record for a mile and an eighth on turf at Santa Anita Park in Arcadia, California.

Kostroma was bred in Ireland by Valerio Ltd. in partnership with trainer Tommy Stack. Out of the mare Katie May, whose sire was the 1967 English Horse of the Year, Busted, she was sired by Caerleon, a two-time leading sire in Great Britain & Ireland and son of English Triple Crown champion Nijinsky.

At age three, Kostroma made a winning debut on May 20, 1989, for owner Robert Sangster and trainer Tommy Slack in the Glengarrif Fillies Maiden at Ireland's Curragh Racecourse. She raced four more times that year without another win, but at age four won her 1990 debut, taking the Mooresbridge Stakes at the Curragh. She went on to win the Ballycullen Stakes, Brownstown Stakes and Desmond Stakes before being sent to California to compete in the November 4, 1990, Grade I Yellow Ribbon Invitational Stakes at Santa Anita Park. Kostroma finished a distant eighth to longshot winner Plenty of Grace.
