Table tennis at the 2020 Summer Paralympics – Men's individual – Class 5

The Men's individual table tennis – Class 5 tournament at the 2020 Summer Paralympics^[1] in Tokyo took place from 25 to 29 August, 2021, at the Tokyo Metropolitan Gymnasium. Classes 1–5 were designated for athletes with physical impairment affecting their legs, who competed in a sitting position. The lower the classification number, the greater the impact of the impairment on the athlete's ability to compete.

In the preliminary stage, athletes competed in four groups of three. Winners and runners-up of each group qualified for the knock-out stage. In this edition of the Games, no bronze medal match was held. Losers of each semifinal were automatically awarded a bronze medal.
