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

This is a listing of the '''history of the world record for the 50 metres [[backstroke]]''' [[Swimming (sport)|swimming]] event. Swimming world records are maintained by [[World Aquatics]], the international sports federation which oversees the sport. World records are recognized only in [[long course]] (50m) and [[Short course (swimming)|short course]] (25m). Like the 50 m breaststroke, 50 m butterfly, and the 50 m backstroke, world record status and monitoring for this event first began in the 1990s.
