The men's heavyweight boxing competitions at the 2018 Commonwealth Games in Gold Coast, Australia took place between 6 and 14 April at Oxenford Studios.

Heavyweights were limited to those boxers weighing less than 91 kilograms.

Like all Commonwealth boxing events, the competition was a straight single-elimination tournament.

Both semifinal losers were awarded bronze medals, so no boxers competed again after their first loss.

Bouts consisted of three rounds of three minutes each, with one-minute breaks between rounds.
