Sofya Andreyevna Zhuk ({{lang-rus|Софья Андреевна Жук|p=ˈsofʲjə ɐnˈdrʲejɪvnə ˈʐuk}}; born 1 December 1999) is a Russian tennis player, who won the 2015 Wimbledon Junior Girls' title.^[1] Her best win to date has been an ITF $60,000 tournament in Turkey, where she beat the home favourite Ipek Soylu in the final.

When she won her first tournament at Shymkent, she became only the 17th 14 year old in ITF history to win an open tournament at that age, joining a group which includes former World No. 1s Justine Henin and Dinara Safina.

In 2015, Zhuk competed as an unseeded 15-year-old at Wimbledon, where she won the Junior Girls' title against fellow Russian and No.12 ranked junior Anna Blinkova in straight sets, 7–5, 6–4. Zhuk did not drop a set in the whole Wimbledon tournament.^[2] Zhuk became only the second Russian to win the Junior Wimbledon Girl's title, following the 2002 final when Vera Dushevina defeated compatriot Maria Sharapova.

She made her WTA singles main draw debut at the 2016 Miami Open, where she received a wildcard into the main draw. She lost in straight sets to Zhang Shuai in the first round.

2018

Zhuk reached the second round of qualifying at the Australian Open, losing to Magdalena Frech of Poland, before heading to Newport Beach in California for their inaugural WTA 125K tournament. She reached her first WTA final in this event where, after taking the first set, she eventually fell to American Danielle Collins, six years her senior, in three sets, 2-6, 6-4, 6-3.

Collins was her nemesis again when they played at Indian Wells, after both had defeated seeded players. Zhuk recorded her very first WTA tour win when she defeated Alizé Cornet in the first round, and followed that by beating 18th seed Magdalena Rybarikova in the second round. Zhuk's second to last service game in that match took well over 20 minutes, with 12 deuces and 30 points. Rybarikova saved 11 match points during the game, before finally winning on only her second break point. Zhuk promptly broke back, and then served out to win 6-3, 2-6, 7-5. Collins, though, having beaten 15th seed Madison Keys in the second round, always had the advantage in their third round clash, winning 6-4, 6-4. Zhuk nevertheless reached her career-high ranking of 123 after this defeat. She then went to the Premier Mandatory tournament in Miami, where she lost in the first round of qualifying.

In the European Grand Slam tournaments, she lost in the first qualifying round of the French Open to Valentini Grammatikopoulou, and in the final qualifying round for Wimbledon to Vitalia Diatchenko, having had her revenge on Grammatikopoulou in the first round.
