Lesia Viktorivna Tsurenko (Ukrainian: Леся Вікторівна Цуренко; born 30 May 1989) is a Ukrainian professional tennis player. Tsurenko has won four singles titles on the WTA Tour, as well as ten singles and eight doubles tournaments on the ITF Women's Circuit. On 18 February 2019, she reached her best singles ranking of world No. 23. On 28 May 2018, she peaked at No. 115 in the WTA doubles rankings.

In 2013, Tsurenko reached the semifinals of the WTA Premier Brisbane International tournament, after entering the draw as a lucky loser replacing Maria Sharapova; she defeated Jarmila Gajdošová and Daniela Hantuchová before losing in three sets to Anastasia Pavlyuchenkova. Having qualified for the main draw of the Australian Open, she again faced Pavlyuchenkova, the 24th seed. This time, Tsurenko won in three sets. She then beat fellow qualifier Daria Gavrilova in the second round, but lost to Caroline Wozniacki in the third. She continued her good run of form on the North American hardcourts, as she reached the third round at the Indian Wells Open as a qualifier; she defeated Ayumi Morita and Yaroslava Shvedova before falling to Petra Kvitová. She reached a new career-high ranking of No. 60 in the world.

After nearly falling out of the world's top 200 prior to Wimbledon in 2014, Tsurenko experienced a mid-career revival. After qualifying for Wimbledon, she defeated Dinah Pfizenmaier to set up a second-round meeting with Simona Halep; Tsurenko pushed the No. 2 seed to three sets before losing out on a possible third-round appearance. She did, however, proceed to reach her first final on the ITF Circuit in nearly two years, losing the Vancouver Open final to Jarmila Wolfe, in three sets. She also reached the semifinals of the Tashkent Open before losing to eventual champion Karin Knapp. Her late-season run ensured she'd finish inside the top 100 for the second year in a row.

In 2015, Tsurenko reached the quarterfinals of the Indian Wells Open, again as a qualifier, defeating Annika Beck, Andrea Petkovic, Alizé Cornet and Eugenie Bouchard before retiring against Jelena Janković in the quarterfinals due to an ankle injury she suffered in defeating Bouchard. After again reaching the second round of Wimbledon and losing to Irina-Camelia Begu, Tsurenko won her first career singles title in Istanbul, defeating Urszula Radwańska in the final. As a result, she reached a new career-high ranking of world No. 47. She qualified for the Canadian Open in Toronto by beating Nicole Gibbs and Lara Arruabarrena, and then defeated Yanina Wickmayer, Wimbledon finalist Garbiñe Muguruza and Carina Witthöft, before succumbing to Sara Errani in the quarterfinals.

Her good form continued at the Connecticut Open. As a lucky loser, replacing Simona Halep, she defeated fifth seed Karolína Plíšková in the quarterfinals, in straight sets. In the semifinals, she eventually lost to French Open finalist, Lucie Šafářová. Tsurenko found revenge one week later at the US Open, defeating the sixth seed Šafářová in the first round. However, she lost to Varvara Lepchenko in round two. This performance allowed her to reach 33rd place in the world rankings at the end of the year.

After a struggle in the first half of the year, Tsurenko made her first major fourth round at the US Open, after beating Irina-Camelia Begu and Dominika Cibulková, before losing to defending finalist, Roberta Vinci. Two weeks later, she won her second WTA Tour singles title in Guangzhou by defeating Jelena Janković in the final.

Tsurenko won her third career singles title in Acapulco, defeating Kristina Mladenovic in the final. After Wimbledon, she reached a new career-high ranking of No. 29.

She defended her title in Acapulco as her fourth singles title by beating Stefanie Vögele in the final. In Cincinnati, she made her first Premier Mandatory quarterfinal appearance in three years, after beating Danielle Collins, Garbiñe Muguruza, and Ekaterina Makarova en route, before losing to Simona Halep.
