Trampoline, an elevated resilient webbed bed or canvas sheet supported by springs in a metal frame and used as a springboard for tumbling. Trampolining, or rebound tumbling, is an individual sport of acrobatic movements performed after rebounding into the air from the trampoline.

Although rebound tumbling has existed for centuries, it did not achieve wide popularity until the 20th century, when it became a featured attraction performed by circus acrobats. The modern sport was born in 1936 with the development of the present-day trampoline by American gymnast George Nissen.
