Ju Wenjun (; born 31 January 1991)[1] is a Chinese chess grandmaster. She is the current Women's World Chess Champion. In March 2017 she became the fifth woman to achieve a rating of 2600.[2] She is a four-time Women's World Chess Champion, having won the title first in May 2018 (against Tan Zhongyi). She then defended her title in November 2018 (against Kateryna Lagno), 2020 (against Aleksandra Goryachkina), and 2023 (against Lei Tingjie).[3]
Ju started learning to play chess at the age of seven.[4]
In December 2004, Ju Wenjun placed third in the Asian Women's Chess Championship in Beirut.[5] This result qualified her to play in her first Women's World Chess Championship in 2006. She competed in this event also in 2008, 2010, 2012, 2015 and 2017.
She won the Women's Chinese Chess Championship in 2010 and 2014.[6] In July 2011 she won the Hangzhou Women Grandmaster Chess Tournament undefeated with a score of 6½/9 points, ahead of the then women's world champion Hou Yifan.[7] In October 2011 she took the second place at the Nalchik stage of the FIDE Women's Grand Prix 2011–12 with 7/11, ranked only after her compatriot Zhao Xue; her performance was enough to acquire her third and final norm required for the Grandmaster title.[8] However, one of the three norms was missing the signature of the arbiter, disqualifying her for consideration for the title.[9]
From June 18 to July 2, 2014, in the 5th stage of the FIDE Women's Grand Prix 2013–14 held in Lopota Resort, Georgia she finished jointly second with Elina Danielian and a 7/11 score. This marks her fourth GM norm. In the 6th stage of the FIDE Women's Grand Prix 2013–14 held in Sharjah, United Arab Emirates, from August 24 to September 7, 2014 she placed joint first with Hou Yifan with a score of 8½/11, winning the event thanks to a better tiebreak score.
In November 2014, FIDE awarded her the GM title in the 4th quarter Presidential Board meeting in Sochi, Russia.[10] With six GM norms, including three norms from the Women's Grand Prix (1 from each series), she is now a fully fledged grandmaster, China's 31st grandmaster and the 31st woman to hold the title. Also in 2014, she tied for first with Lei Tingjie in the 4th China Women Masters Tournament in Wuxi.[11]
In December 2017, Ju won the Women's World Rapid Chess Championship in Riyadh,[12] and won in the same championship held in St. Petersburg in December 2018,[13] scoring 11½/15 (+8=7)[14] and 10/12 (+8=4),[15] respectively.
Ju earned the biggest win of her career in the fifth round of the Tata Steel Chess Tournament 2024, defeating then world number 6 Alireza Firouzja.[16] She also drew World Champion Ding Liren in the final round, and eventually finished the tournament in 10th with 4½/13 (+1-5=7), gaining 9.7 rating points.
Ju Wenjun won FIDE Women's Grand Prix 2015–16.[17] [18] This qualified her for a match for the Women's World Chess Championship 2017 against incumbent champion Tan Zhongyi. Ju won the match with a score of 5½ - 4½ in May 2018, becoming the Women's World Chess Champion.
The next Women's World Chess Championship was decided by a 64-player knockout tournament. Ju won the tournament, which was held in November 2018, retaining her title.[19] Since then, she has defended her title in matches twice: first against Aleksandra Goryachkina in the Women's World Chess Championship 2020 (6-6; 2½–1½ in tiebreaks), then against Lei Tingjie in the Women's World Chess Championship 2023 (6½-5½).
