Mark Thomas (born 1963), is a former weightlifter who competed for Great Britain and England.
Thomas represented Great Britain in the 1988 Summer Olympics.
He represented England and won three gold medals in the 110 kg sub-heavyweight division, at the 1990 Commonwealth Games in Auckland, New Zealand. The three medals were won during an unusual period when three medals were awarded in one category (clean and jerk, snatch, and combined) which invariably led to the same athlete winning all three of the same colour medal.
