50 metres, or 50-meter dash, is a sprint event in track and field, featured as an alternative to the 60 metres running event. It is a relatively uncommon non-championship event for indoor track and field, normally dominated by the best outdoor 100 metres runners. At outdoor athletics competitions it is used in the Special Olympics but otherwise a rare distance. The World Masters Rankings has recorded the event since the 2010s.
Records and personal bests in the 50 metres are frequently achieved in February and March as these dates coincide with the indoor athletics season.
