Anthea Dorine Stewart (born November 20, 1944) is a former field hockey player from Zimbabwe, who was a member of the national women's team that won the gold medal at the 1980 Summer Olympics in Moscow.
Because of the boycott of the United States and other countries, only one team was available to compete in the women's field hockey tournament: the hosting USSR team. 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.
Stewart is the mother of international diver Evan Stewart, who competed in three consecutive Summer Olympics for his native country, starting in 1992 in Barcelona, Spain.
