Wu Chuan, courtesy name Wu Ching-yuan, better known by the Japanese pronunciation of his courtesy name, Go Seigen , was a Chinese-Japanese master of the game of Go. He is considered by many players to have been the greatest Go player in the 20th century.

Go is an abstract strategy board game for two players in which the aim is to fence off more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go, and over 20 million current players, the majority of whom live in East Asia.
