The Men's Greco-Roman bantamweight at the 1968 Summer Olympics as part of the wrestling program were held at the Insurgentes Ice Rink. The bantamweight was the second-lightest weight class, allowing wrestlers up to 57 kilograms.
The competition used a form of negative points tournament, with negative points given for any result short of a fall. Accumulation of 6 negative points eliminated the wrestler. When only two or three wrestlers remain, a special final round is used to determine the order of the medals.
Results from the preliminary round are carried forward into the final (shown in yellow).
