Mark Thomas (born 23 July 1983) is an English professional retired ice hockey defenceman who played for the Sheffield Steelers.

Thomas took up ice hockey much later than most players but was able to thrive due to his natural talent and physical abilities.

During his first season, Thomas played in 22 games and totaled 63 penalty minutes as well as helping out the offence with seven points.

Thomas established himself as a key part of the Steelers defence, and was a rare British star player surrounded by foreign imports.

On 6 May 2015, it was announced that Thomas was returning to his hometown team, the EPL's Manchester Phoenix, who he had previously played for in their inaugural season in 2003–04.
