Spencer Dunn (born 25 November 1969) is an English former professional snooker player.
Dunn was born in 1969, and turned professional in 1992. At the end of the 1992/1993 season, having failed to progress beyond the qualifying rounds of any tournament, he entered the 1993 World Championship. There, he won his first qualifying match against Ian Bullimore 5âÂÂ1, before embarking on a run of another ten successive victories to reach the last 32 at the Crucible Theatre. Having beaten Bullimore, Dunn defeated Colin Mitchell by the same scoreline, Elliott Clark 5âÂÂ4, Neil Selman 5âÂÂ1, Julian Goodyear 5âÂÂ1, Kieran McAlinden 5âÂÂ4, Mehmet Husnu 5âÂÂ2, Bill Oliver 10âÂÂ2, Colin Roscoe 10âÂÂ7, Dave Harold 10âÂÂ7 and Mark Bennett 10âÂÂ9, setting up an encounter with Nigel Bond. In the event, Dunn was unable to progress any further; he trailed 1âÂÂ6 and, although he recovered to 4âÂÂ8, could not prevent himself from losing 4âÂÂ10.
Dunn's eleven qualifying wins to reach the main stages of the World Championship remain a tournament record; incidentally his nearest challengers, John Giles and Ronnie O'Sullivan who won ten matches, also achieved their feats in the 1993 event.
Dunn failed to progress further than the last 96 of any tournament in the following two seasons; having been ranked 145th in the world for the 1994/1995 season, he lost his professional status in 1995.
