3D World Boxing is a boxing video game released in 1992 for the Amiga, Commodore 64 and MS-DOS by Simulmondo. In the screenshots of the Commodore 64 version it is titled Boxing Champion. It is part of a group of sports simulations together with 3D World Soccer and 3D World Tennis from the same year.

You can face the category championship, a single match or a two-player match. The computer opponents are selectable from different boxers with different characteristics and different cash value if the player defeats them. In the championship, between one bout and another, you can also change the characteristics of your boxer, distributing training as desired among the various skills, represented by extendable bars. They are aggression, initiative, energy (not present on the Commodore 64), endurance, power, killer instinct, defense and attack.

The ring is shown from the side, in perspective, and in the Amiga version there is also limited horizontal scrolling. Boxers can move in all directions and during the action they automatically rotate on themselves, always facing each other from all angles. The referee is not visible during the match. There's a fairly small set of possible actions, including hugging, and it's not possible to strike while moving. Each boxer has an energy bar at the end of which he is knocked down, otherwise the victory is on points.
