Lulu Sun (born 14 April 2001) is a Swiss New Zealand tennis player. She has a career-high singles ranking by the WTA world of No. 151, achieved on 26 February 2024, and a best doubles ranking of No. 318, reached on 18 March 2024.
History
Sun represented Switzerland as a junior, finishing runner-up with Violet Apisah in the 2018 Australian Open girls' doubles, but also played under the New Zealand flag at junior Wimbledon that year, losing in the second round in singles and the first round in doubles.
She played college tennis at the University of Texas at Austin and turned pro after graduating in 2022.[]
She won her first big ITF title at the 2022 Saint-Gaudens Open, partnering Fernanda Contreras in doubles, and made her WTA Tour main-draw debut at the 2022 Morocco Open just two days later, where she received a wildcard into the singles draw.
She made her Grand Slam debut at the 2024 Australian Open, and recorded her first win at the WTA 1000 level at the 2024 Dubai Tennis Championships as a wildcard following the retirement of Paula Badosa. As a result she moved to a new career-high singles ranking of No. 151 on 26 February 2024.
In March 2024 Sun announced her intention to play under the New Zealand flag as part of the New Zealand team for the 2024 Billie Jean King Cup.
