Karl Muggeridge born 20 April 1974 in Tweed Heads, New South Wales, Australia is a former professional motorcycle racer.

Ten Kate expanded its Superbike World Championship team to 2 Honda Fireblade bikes for 2005, and Karl was moved up to join Chris Vermeulen, who won the WSS title for Ten Kate in 2003 and challenged for the WSBK crown as a series rookie in 2004.

In 2006 a back injury caused him to miss the Valencia round[1] and he again failed to score a podium finish, despite strong qualifying runs including 3rd at Brands Hatch.

He also raced a couple of rounds in the British Superbike Championship for the HM Plant, Honda as a replacement rider for the injured Glen Richards.
