Fan Zhengyi (born 27 January 2001) is a Chinese snooker player.
In July 2017, Fan won five out of the last six frames to beat top seed Luo Honghao 7–6 and win the IBSF World Under-21 Snooker Championship at the tournament held in China. With this victory he was awarded a two-year Main Tour card for the professional snooker tour.
He competed at the 2018 World Snooker Team Cup representing China with Zhang Jiankang but they lost to India 2–3 in the Round of 16.
Fan has a very unusual technique. He is very left-eye dominant, and when playing the shot, his cue is to the left of his head. He has been coached by Roger Leighton.
Amateur finals: 2 (1 title, 1 runner-up)
