The Men's Singles 2 table tennis competition at the 2004 Summer Paralympics was held from 18 to 21 September at the Galatsi Olympic Hall. Classes 1-5 were for athletes with a physical impairment that affected their legs, who competed in a sitting position. The lower the number, the greater the impact the impairment was on an athlete’s ability to compete. The event was won by Jan Riapos, representing Slovakia.
