Maria Esther Andion Bueno (born October 11, 1939) is a former professional tennis player from Brazil. During her 11-year career (plus a two-year comeback in 1976-77), she won 19 Major titles (seven singles, 11 women's doubles, one mixed doubles).

In 1960, Bueno became the first woman ever to win all four Grand Slam double titles in one year (three with Darlene Hard and one with Christine Truman Janes).

Bueno began playing tennis at a very young age and, without having received any formal training, won her first tournament at age 12. She was 14 when she captured her country’s women's singles championship.

Joining the international circuit in 1958, Bueno won the singles title at the Italian Championships and the first of her Grand Slam titles, capturing the women's doubles at Wimbledon with Althea Gibson.

The following year, Bueno won her first singles title at Wimbledon, defeating Darlene Hard in the final. She also won the singles title at the U.S. Championships, earning the World No. 1 ranking for 1959 and the Associated Press Female Athlete of the Year award. Bueno was the first non-North-American woman (she is an American - South American - woman) to capture both Wimbledon and the U.S. Championships in the same calendar year. In her native Brazil, she returned as a national heroine, honored by the country’s president and given a ticker-tape parade on the streets of São Paulo.
