Emma Raducanu MBE (/ræduˈkɑːnuː/;^[3] born 13 November 2002) is a British professional tennis player. She reached a career-high ranking of No. 13 by the Women's Tennis Association (WTA) and is the current British No. 1. Raducanu is the reigning US Open champion and the first British woman to win a Grand Slam singles title since Virginia Wade in the 1977 Wimbledon Championships. She is considered a baseline player, known for her powerful, flat groundstrokes and aggressive return of serve.

Raducanu was born in Toronto and raised in London. She made her WTA Tour debut in June 2021. With a wildcard entry at Wimbledon, ranked outside the top 300, she reached the fourth round in her first major tournament. At the US Open two months later, Raducanu became the first singles qualifier in the Open Era to win a Grand Slam title, beating Leylah Fernandez in the final.

She won three rounds of qualifying matches and seven matches in the tournament, without losing a set. This was the second Grand Slam tournament of her career; she holds the record for the fewest majors played before winning a title.
