Stuart Pettman (born 24 April 1975) is an English former professional snooker player and author.

He started 2007/2008 strongly, reaching the last 16 of the opening Shanghai Masters (winning 4 matches before benefitting from Ronnie O'Sullivan's withdrawal) and then qualifying for the final stages of the Grand Prix by winning all 7 group games.

His form tailed off after this, but he had a strong run in the 2009 China Open, defeating Mark Allen, Ali Carter and Graeme Dott to reach his first career semi-final.

Following 10–2 defeats by Mark Williams and Stephen Hendry in 2003 and 2004 respectively, this means Pettman's win–loss ratio of frames played at the Crucible is 5–30.

He wrote a book entitled Stuart Pettman: As Sometimes Seen On TV about his experiences on the World Snooker Tour.
