{{main|List of world records in swimming}}

The first world record in the men's 400 metres freestyle in long course (50 metres) swimming was recognised by the International Swimming Federation (FINA) in 1908. In the short course (25 metres) swimming events the world's governing body recognizes world records since 3 March 1991.

The drop in world record times in 2008–2009 coincided with the introduction of polyurethane suits from Speedo (LZR, 50% polyurethane) in 2008 and by Arena (X-Glide), Adidas (Hydrofoil) and Italian swimming suit manufacturer Jaked (all 100% polyurethane) in 2009. FINA's ban on non-textile suit came into effect in January 2010.{{cite news|title=Hi-tech suits banned from January|url=http://news.bbc.co.uk/sport2/hi/other_sports/swimming/8161867.stm|newspaper=BBC News/BBC Sport|date=2009-07-31 |archive-url=https://web.archive.org/web/20120801110745/http://news.bbc.co.uk/sport2/hi/other_sports/swimming/8161867.stm|archive-date=August 1, 2012|access-date=August 11, 2012|url-status=bot: unknown}} FINA also released a list of approved suits.

|{{note|Short Course}}As of 1 May 1957, World Aquatics required records to be set in a 50-metre pool. This resulted in the annulment of Murray Rose's world record of 4:25.9. As John Marshall's 4:26.9 and Ford Konno's 4:26.7 were also set in 25-metre pools, the world record was reverted to Rose's 4:27.0 from 1956.
