Evonne Fay Goolagong Cawley AC MBE (née Goolagong; born 31 July 1951) is an Australian former professional tennis player. She was ranked as the world No. 1 in women's singles by the Women's Tennis Association (WTA), and was one of the world's leading players in the 1970s and early 1980s. Goolagong won 86 WTA Tour-level singles titles, including seven singles majors, and 46 doubles titles, including seven doubles majors.

At the age of 19, Goolagong won the French Open singles and the Australian Open doubles championships (the latter with Margaret Court). She won the women's singles tournament at Wimbledon in 1971, becoming the 2nd woman in the Open Era to complete the Channel Slam (winning the French Open and Wimbledon in the same year). Goolagong is the only woman to beat Court, Martina Navratilova, and Chris Evert in a grand slam final. In 1980 she won Wimbledon again, this time as a mother and becoming the first mother to win the title in 66 years. She represented Australia in three Fed Cup competitions, winning the title in 1971, 1973 and 1974, and was Fed Cup captain for three consecutive years. After retiring from professional tennis in 1983, Goolagong played in senior invitational competitions, endorsed a variety of products, worked as a touring professional, and held sports-related leadership roles.

Goolagong was named Australian of the Year in 1971. She was appointed as a Member of the Order of the British Empire in 1972 and as an Officer of the Order of Australia in 1982. Goolagong was inducted into the Sport Australia Hall of Fame in 1985, the International Tennis Hall of Fame in 1988, and the Aboriginal Sporting Hall of Fame in 1989. She leads the Goolagong National Development Camp for Indigenous boys and girls, which encourages Indigenous youth to stay in school.

Evonne is the third of eight children from an Australian Aboriginal (Wiradjuri) family. Her father, Ken Goolagong, was a sheep shearer and her mother, Melinda, was a homemaker. Evonne was born in Griffith, New South Wales, and grew up in the small country town of Barellan.

Goolagong grew up during the time of the stolen generations in Australia, and was directly impacted by it:

Lucky not to be taken away by the stolen generation because I've had to hide a few times under the bed. We visited my cousin in Griffith, which is where I was born, in the mission there. Every time a shiny car would come down the road, my mum used to say "you better run and hide, the welfare man's going to take you away." So I remember hiding very nervously under the bed, 'cause I didn't want to get taken away.

Despite the widespread disadvantage and prejudice Aboriginal people experienced in Australia, Goolagong was able to play tennis in Barellan from childhood, thanks to an area resident, Bill Kurtzman, who saw her peering through the fence at the local courts and encouraged her to come in and play.

In 1965, Vic Edwards, the proprietor of a tennis school in Sydney, was tipped off by two of his assistants, travelled to Barellan to take a look at the young Goolagong, and immediately saw her potential. He persuaded her parents to allow her to move to Sydney, where she attended Willoughby Girls High School. There, she completed her School Certificate in 1968 and, at the same time, lived with the family of Edwards, who had become her legal guardian, coach, and manager.
