Wilbur Slabber (born 2 December 1980) was a Namibian cricketer. He was a right-handed batsman and a right-arm offbreak bowler. He represented the Namibian Under-19s cricket team in two consecutive Under-19 Cricket World Cups in 1998 and 2000.
Finishing not out in his first innings against Denmark in January 1998, he fluctuated between the lower and lower-middle order during the following World Cup in 2000, playing higher against stronger opposition.
Slabber made his first appearance for Namibia for over two years in a List A match against Canada in 2007, bowling five overs. Slabber's debut first-class appearance came in the South African Airways Provincial Challenge against Griqualand West in November 2007.
