Thomas Bellchambers (born 9 July 1989) is a professional Australian rules footballer playing for the Essendon Football Club in the Australian Football League (AFL).
He played for the Tasmanian Devils in the TAC Cup, and was drafted with pick 8 in the 2007 pre-season draft.
He made his debut against Hawthorn in Round 11 of the 2008 AFL season.
Bellchambers, along with 33 other Essendon players, was found guilty of using a banned performance enhancing substance, thymosin beta-4, as part of Essendon's sports supplements program during the 2012 season.
He and his team-mates were initially found not guilty in March 2015 by the AFL Anti-Doping Tribunal, but a guilty verdict was returned in January 2016 after an appeal by the World Anti-Doping Agency.
He was suspended for two years which, with backdating, ended in November 2016; as a result, he served approximately fourteen months of his suspension and missed the entire 2016 AFL season.
