Table tennis at the 2020 Summer Paralympics – Men's individual – Class 3

The Men's individual table tennis – Class 3 tournament at the 2020 Summer Paralympics in Tokyo is taking place between 25 and 29 August 2021 at Tokyo Metropolitan Gymnasium. Classes 1–5 are for athletes with a physical impairment that affected their legs, and who compete in a sitting position. The lower the number, the greater the impact the impairment is on an athlete's ability to compete.

In the preliminary stage, athletes competed in seven groups of three. Winners and runners-up of each group qualified for the knock-out stage, with the best two group winners receiving a bye to the quarter-finals and the other 12 teams playing from the round of 16. In this edition of the Games, no bronze medal match will be held. Losers of each semifinal will automatically be awarded a bronze medal.
