跳伞指人利用降落伞从具有一定高度的航空器、跳伞塔、摩天大楼等高空处跳下来。

1797年10月22日，法国青年安德烈-雅克·加纳林在巴黎借助热气球升至100米（330英尺）的高空，完成人类史上首次成功的跳伞。

Parachuting, or skydiving, is a method of exiting an aircraft and returning to Earth with the aid of gravity, then slowing down during the last part of the descent by using a parachute. It may involve more or less free-fall, a time during which the parachute has not been deployed and the body gradually accelerates to terminal velocity.
