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.
