# Swimming at the 2024 Summer Olympics – Men's 4 × 100 metre medley relay

The men's 4 × 100 metre medley relay event at the 2024 Summer Olympics was held on 3 and 4 August 2024 at Paris La Défense Arena, which was converted to a swimming pool for the swimming events. Since an Olympic size swimming pool is 50 metres long, each swimmer had to swim two lengths of the pool with their respective stroke.
China won gold, with the United States finishing second and France third. This marked the first time since the event's inclusion in the 1960 Olympics that the U.S. competed in the men's 4 × 100 metre medley relay and did not win gold.
