Thomas Leon Preston Campbell OAM[5][6][7] (born 7 June 1977) is an Australian former professional rugby league footballer who played as a five-eighth or fullback in the National Rugby League (NRL) for the Cronulla-Sutherland Sharks, the Penrith Panthers (with whom he won the 2003 NRL premiership) and the Gold Coast Titans.

His electrifying speed and side-step combined with his diminutive stature and humility quickly endeared him to Cronulla fans.

Combining with David Peachey and pivot Adam Dykes, the trio formed a devastating combination on the field as Cronulla pushed forward and made a serious bid for its 2001 finals campaign including one memorable game when Premiership favourites the Newcastle Knights were soundly beaten by the Sharks.

After several disastrous games and seemingly very little interest in playing, he was dropped to reserve grade and, stating his desire to return to the position he had made his own, requested a release from Cronulla which was eventually granted in early August 2002.

As 2003 NRL premiers, the Panthers travelled to England to face Super League VIII champions, the Bradford Bulls in the 2004 World Club Challenge.

In 2005, with two seasons still to play with the Panthers, Campbell was the inaugural signing for the newly admitted NRL club, Gold Coast Titans.

In 2009 he played halfback, five-eighth and fullback due to the injuries to players such as Scott Prince and Mat Rogers.
