Ann-Mary Gwynne Grant (born May 6, 1955) is a former field hockey player from Zimbabwe, who captained the national team that won the gold medal at the 1980 Summer Olympics in Moscow. Because of a boycott by western European, Australasian and other countries, the Women's Field Hockey Tournament contained fewer teams than normal. A late request was sent to the government of Zimbabwe, which quickly assembled a team less than a week before the competition started. To everyone's surprise they won, claiming Zimbabwe's only medal in the 1980 Games. Grant captained the team.
