Relkino (21 April 1973 – after 1989) was a British Thoroughbred racehorse and sire. He was the highest-priced European of his generation and won four of his sixteen races between July 1975 and October 1977. After winning one race as a two-year-old in 1975 he showed improved form in the early part of the following year, winning the 2000 Guineas Trial Stakes and finishing second to Empery in the Epsom Derby.
