Hou Yifan (Chinese: 侯逸凡; pinyin: Hóu Yìfán ) (born 27 February 1994, Xinghua, Jiangsu, China) is a Chinese chess grandmaster and former chess prodigy. She has been the Women's World Chess Champion three times, the youngest ever to win the title, as well as the youngest female player ever to qualify for the title of Grandmaster.
At the age of 12, Hou became the youngest player ever to participate in the FIDE Women's World Championship (Yekaterinburg 2006) and the Chess Olympiad (Torino 2006). In June 2007, she became China's youngest National Women's Champion ever. She achieved the titles of Woman FIDE Master in January 2004, Woman Grandmaster in January 2007, and Grandmaster in August 2008. In 2010, she won the 2010 Women's World Championship in Hatay, Turkey at age 16. She has since been the Women's World Chess Champion about half the time: she won all the championships in which the title was decided by a match without losing a game (in 2011, 2013 and 2016, with a total of ten wins to zero losses and 14 draws against three different opponents), but was either eliminated early or declined to participate in the later championships in which the title was decided by a knockout tournament (in 2012, 2015 and 2017).
Hou is the third woman ever to be rated among the world's top 100 players, after Maia Chiburdanidze and Judit Polgár, in the August 2014 FIDE rating list. She is widely regarded as the best active female chess player, "leaps and bounds" ahead of her competitors. She is the current top-rated female player, 94 points ahead of Anna Muzychuk.
Hou started playing chess regularly at the age of five, but was already fascinated by the game when she was three years old. Hou's father, Hou Xuejian, a magistrate, often took his young daughter to a bookstore after dinner. He noticed that the little girl liked to stare at glass chess pieces behind the window. He later bought his daughter her first chess set. The 3-year-old was able to beat her father and grandmother after a few weeks. In 1999, her father engaged a chess mentor, IM Tong Yuanming, for his 5-year-old daughter. Tong later said that Hou was an unusual talent, showing "strong confidence, distinguished memory, calculating ability and fast reaction". Hou herself said that she took up chess because she was fascinated by the pieces.
In 2003, Hou played against the chief coach of the Chinese National men's and women's chess teams, Ye Jiangchuan, for the first time. The chess master was surprised that the 9-year-old could identify almost all of his weak moves. "Then I knew she was an exceptional genius", Ye said. That year, Hou became the youngest member of the national team and won first place at the World Youth Championship for girls under age ten. In June 2007, she became China's youngest ever national champion.
She was admitted to the National Chess Center, an academy for young talented players from all over the country, in Beijing when she was ten, with leading Chinese grandmasters Ye Jiangchuan and Yu Shaoteng as her trainers. In order to better support her chess career, her family relocated to Beijing in 2003. Hou's mother, a former nurse, accompanies her daughter on the international tournament circuit. Hou is homeschooled and lists her interests as reading and studying, and her favorite chess player as Bobby Fischer. Her mother Wang Qian accompanied her to many international tournaments when she was young.
Hou has attempted to balance chess with life outside of it. She enrolled in Peking University in 2012, studying International Relations, against the wishes of her trainer. She took a full course load and participated in many extracurricular activities; after graduation she applied to and was accepted by the University of Chicago for a master's in social work. Compared to the best professional male players who dedicate their lives to chess, Hou's split focus puts her at a disadvantage, and as a consequence her results against them have been lackluster. These competitors give her credit for what she has achieved in spite of her lack of preparation, and for her life outside of chess. However, they recognize that while Hou can probably remain the best female player in the world without extra effort, she cannot compete with the best male players unless she dedicates herself to chess. Hou is aware of this as well, but has yet to make the choice.
She won her first international tournament when she came first (9½/11; +8 =3 -0, TPR 2121) in the girl's under-10 section of the World Youth Championship in Halkidiki, Greece in October–November 2003. In November, she made her debut in the National Women's Chess Championship, held at Shanwei, Guangdong. She finished in 14th place with 3½/9 with a performance rating of 2202.
On 1 January 2004, she received her first International FIDE rating of 2168, which automatically qualified her for the title of Woman FIDE Master. In April, she competed at the Chinese Team Chess Championship (Women's) in Jinan, Shandong. She scored 1½/7 (TPR 2096) having faced an average opposition rating (Rc) of 2316.

In October, she managed to qualify for the World Women's Chess Championship to be held in March 2006. Despite being rated only 2220 and ranked women's number 28 in her own country, she qualified by winning the Chinese Women's Zonal (3.5) tournament, scoring 6/9 points with a performance rating of 2526 against a rating opposition of 2401, ahead of several better-known Chinese players.
The sixth World Team Chess Championship was staged in Beersheva, Israel from 31 October-11 November. China fielded two teams – the men's and women's, which was only the second time in the championship history where a women's team competed in what has traditionally been a male team event. This was Hou Yifan's first major team tournament and she was the youngest participant there at 11 years of age. She played as second reserve and finished with 0/3. The Chinese women's team drew one match and lost all their others (+0 =1 -7) finishing last. The tournament was won by Russia, with China (men's) coming in second and Armenia third.

In July–August, she performed badly at what has been traditionally the strongest women's tournament, the North Urals Cup in Krasnoturinsk, Russia. Although seeded third, she failed to win a game scoring 3/9 (+0 =6 -3) with a performance rating of 2357. She finished 8th out of 10 players.
In 10–20 August, she played in the China-Russia Summit Match in Ergun, Mongolia. The tournament was a two double round robin Scheveningen, one for men and one for women (category VIII (2444)).

France edged out China 20–16 in the men's event. The women's section was a complete mismatch in terms of Elo ratings in favour of the Chinese and they confirmed this over the board winning 12½–5½. The overall result was China 28½ France 25½. Hou Yifan was again the highest scoring female player with 5/6 and a performance rating of 2498.

This result, together with WGM norms she had earned at the 2005 Zonal 3.5 Women's Championship, the 37th Chess Olympiad and the 2006 Chinese Championship (Women's) won her the WGM title, formally conferred by FIDE in late January 2007.
At the Aeroflot Open in February 2007, a few weeks before Hou's 13th birthday, she played in the A1 group for the first time. Hou started well with two wins out of two, defeating first the Russian IM Nikita Vitiugov (rated 2604) and then the 2001 European Champion, GM Emil Sutovsky of Israel (rated 2629).
