Stuart Mann (born 30 December 1972) is an English former professional snooker player.

At the 2001 World Championship, he defeated Peter McCullagh 10–5, Martin Dziewialtowski 10–9 and Matthew Couch 10–2 to reach the last 64 at a ranking event for the first time; requiring two more victories to make his first appearance at the Crucible Theatre, Mann was drawn against Jonathan Birch, but lost 6–10.

During the 2002/2003 season, Mann reached the final of a tournament for the first time, at Event Two of that year's Challenge Tour series.

He beat six opponents, including Joe Meara, Scott MacKenzie and Mehmet Husnu, but lost 5–6 in the final to Adrian Rosa.

He lost 1–10 to Ding Junhui in qualifying for the 2006 World Championship and, ranked 90th, fell off the tour again at the season's conclusion.
