轻艇激流（Canoe slalom），是一项编列在轻艇(Canoe/Kayak)项目中夏季奥林匹克运动会的正式比赛项目，另一项则是轻艇静水竞速(Canoe sprint)。轻艇激流是一项相当刺激且有看头的运动，选手必须在设计过的人工或天然障碍物河道内，运用控制船艇的技术与激流的对抗下通过设计的18-25组标杆，其中包括6组逆流而上的回旋标杆(呈现红白色)以及顺流而下的直径标杆(呈现绿白色)。目前在欧美国家轻艇激流非常盛行，且具备着刺激效果观赏性的运动。比赛河道约250－400米之间有流速的河道上进行，以计时的方式依序通过设计的标杆路线。

Whitewater slalom (canoe/kayak slalom since November 2008) is a competitive sport where the aim is to navigate a decked canoe or kayak through a course of hanging gates on river rapids in the fastest time possible. It is one of the two kayak and canoeing disciplines at the Summer Olympics, and is referred to by the International Olympic Committee (IOC) as Canoe/Kayak slalom. The other Olympic canoeing discipline is canoe sprint. There is also wildwater, a non-Olympic paddlesport.
