This is a history of the progression of the World Record for the Swimming event: the 200 Butterfly . It is a listing of the fastest-time-ever swum in the event, in both long course (50m) and short course (25m) swimming pool. These records are maintained/recognized by FINA, which oversees international competitive Aquatics.
The long course records are historically older than the short course records: the long course records go back to at least the 1950s, whereas the short course marks having only been recognized since the early 1990s.
