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

The men's 4 × 100 metre freestyle relay event at the 2024 Summer Olympics was held on 27 July 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.
