The men's welterweight boxing competitions at the 2018 Commonwealth Games in Gold Coast, Australia took place between 5 and 14 April at Oxenford Studios.

Welterweights were limited to those boxers weighing less than 69 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.

Beginning this year, the competition was scored using the "must-ten" scoring system.
