World record progression 200 metres freestyle

This is a history of the progression of the world record for the 200 metres freestyle swimming event.

It is a listing of the fastest-times-ever swum in the event, in both long course (50m) and short course (25m) swimming pools.

These records are maintained and recognized by FINA, which oversees international competitive swimming and Aquatics.

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.
