World record progression 4 × 200 metres freestyle relay

This article includes the world record progression for the 4×200 metres freestyle relay, and it shows the chronological history of world record times in that competitive swimming event. The 4×200 metres freestyle relay is a relay event in which each of four swimmers on a team swims a 200-metre freestyle leg in sequence. The world records are recognized by and maintained by FINA ("Fédération Internationale de Natation"), the international competitive swimming and aquatics federation that oversees the sport in international competition.

World records in swimming were first recognized by FINA in 1908. The long course (50-metre pool) world records are historically older than the short course (25-metre pool) records. FINA amended its regulations governing the recognition of world records in 1956; specifically, FINA mandated that only record times that were contested in 50-metre (or 55-yard) pools were eligible for recognition after that time. The short-course world records have been separately recognized since 1991.

The men's 4×200-metre event was first contested at 1908 Summer Olympics in London, but the women's 4×200-metre event didn't appear until the 1996 Summer Olympics in Atlanta. Prior to 1996, the shorter 4×100-metre freestyle relay was the only women's freestyle relay event staged.
