The following table shows the world record progression in the men's 200 metres, as ratified by the IAAF. The current record of 19.19 seconds was set by Usain Bolt at the 2009 World Championships in Athletics.
The IAAF maintained separate records for 200 m over a straight track and over a curved track until 1976, when records for the former were discarded. The IAAF ratified the first record for 200 m on a curved track in 1951. "y" denotes times for 220 yards (201.17 m) which were also ratified for the event.
As of 2018, the IAAF has ratified 24 world records in the event.[1]
