Rui Naiwei (simplified Chinese: 芮迺伟; traditional Chinese: 芮迺偉; pinyin: Ruì Nǎiwěi; born December 28, 1963) is a Chinese professional Go player, once active in South Korea. She is probably the strongest recorded female Go player, and is the only woman to have won one of the major open Go titles.
After starting to play around 1975 (at the age of 11—the age some other players go pro) she became a pro for the Zhongguo Qiyuan in 1985, being promoted all the way to 7-dan that year. She reached 9-dan in 1988, becoming the first woman ever to achieve that rank. After that, Chinese Feng Yun and Korean Pak Chi-eun became the second and third female go players to reach 9 dan, following Rui Naiwei.
Leaving China in 1989, she moved to Japan. While the Nihon Ki-in did not allow her to play in any Japanese tournaments, she was able to make it to the semi-finals of the international Ing Cup in 1992. She spent several years in the San Francisco Bay Area with her husband, then they moved to South Korea (with the help of Cho Hun-hyeon 9-dan), where she has dominated the women's events and has won two open events, always previously won by men: the Guksu (the 43rd open Guksu title in South Korea, 1999) and the Maxim Cup (2004).
Rui's style tends to be extremely aggressive, and often characterized by large scale semeai.
