David McLellan (born 10 January 1970) is a Scottish former professional snooker player.

McLellan reached his first quarter-final at Event 2 of the 1994 Minor Tour, where he defeated nineteen-year-old John Higgins 3–1, Drew Henry 3–0, Scott MacFarlane 3–1 and Robin Hull 5–2, before losing 3–5 to Jason Weston.

McLellan repeated this feat at the next year's edition of the tournament, defeated this time 5–0 by Peter Ebdon.

At the 1997 World Championship, McLellan won five matches to reach the main stages at the Crucible Theatre; he defeated Joe Jogia, Peter Lines and Tony Jones all 10–9, Nick Dyson 10–6 and Neal Foulds 10–9 to set up a meeting with the six-time World Champion Steve Davis in the last 32.

Having lost his professional status in 2001, McLellan entered tour qualifying events the following season to regain it; he was successful, but dropped off the tour once more at the end of the 2002/2003 season, leaving professional snooker at the age of 33.
