Woodstream (14 May 1979 – after 2003) was an American-bred, Irish-trained Thoroughbred racehorse and broodmare. In a racing career which lasted from July 1981 until June 1982, she won four of her six races and finished second one. As a two-year-old she was rated the best filly of her age in Ireland after being unbeaten in four starts. After winning two minor races she was awarded the Moyglare Stud Stakes on the disqualification of Sweet Side and then traveled to England to win the Group One Cheveley Park Stakes. In the following year she finished second in the Irish 1000 Guineas but was retired after running poorly in the Coronation Stakes. She had some success as a broodmare, although she produced no major winners.
