The men's marathon at the 1992 Summer Olympics in Barcelona, Spain, was held on Sunday August 9, 1992.

The event was won by Hwang Young-Cho of South Korea, the nation's first Olympic men's marathon medal.

"[2] Aruba, Bahrain, Cameroon, Liechtenstein, Mauritania, Mongolia, Namibia, San Marino, Slovenia, and Syria each made their first appearance in Olympic men's marathons; some former Soviet republics appeared as the Unified Team in the team's only Summer Games.

The marathon distance of 26 miles, 385 yards was run over a point-to-point route starting at Mataró and finishing at the Olympic Stadium.

The course ran along the Catalan coast, finishing with a "brutal" climb of 150 metres up Montjuïc to the stadium.
