跳台滑雪是一项竞技滑雪比赛，其中，参赛者沿着陡峭的坡道滑雪，该坡道在终点或起飞点向上弯曲。滑雪者从尽头飞跃，试图覆盖尽可能多的水平距离。
自1924年在法国霞慕尼（Chamonix）举办奥运会以来，跳台滑雪就已列入冬季奥运会。在1964年奥运会上增加了第二个更大的山丘之后，该项目便分裂了起来，形成了大山丘跳跃和正常（或小）山丘跳跃。比赛是在精心分级的，准备好的山丘上进行的，并根据距大多数滑雪者可以安全地着陆的起飞点的距离进行分类。大多数高级国际赛事，包括奥运会，都在120米和90米（393.7英尺和295.275英尺）的高度上进行比赛，分别是大山丘和普通山丘。在冬季奥运会上，个人和团体跳台滑雪比赛都将举行。 1925年，国际滑雪联合会（FIS）领导了世界跳台滑雪锦标赛的举办，并于1980年建立了世界杯巡回赛。直到2009年，女子才在FIS世界锦标赛上参加跳台滑雪比赛。2011年，俄罗斯索契2014年冬季奥林匹克运动会的日程安排中又增加了女子正常滑雪跳台。
跳台滑雪是从进场或进站开始的，通常是在脚手架或塔上开始。跳线运动员在蹲伏的位置向下滑行，累积速度（每小时高达100公里（62英里），直到他到达起飞处，然后向外弹起。由于存在以如此高的速度下坡的风险以及同时降落在山脚底部的可能性，法官有权降低跳高起点，以降低跳高运动员的最大潜在速度。
一旦飞向空中，竞争对手就只能依靠身体的姿势来最大化他们的跳跃。直到1990年代初，大多数跳高运动员的首选位置是从脚踝向前倾斜，膝盖伸直，滑雪板保持平行并略微向上倾斜。该位置使风阻最小，并有助于提高空气动力学效果，从而增加了跳跃的时间。然而，在1980年代中期，瑞典跳投运动员扬·博克洛夫（JanBoklöv）展示了一种提供更大举重能力的新技术：V型。通过以相反的方向向外指向雪橇的顶端以形成V形，可以实现此位置。在最初因他的非传统风格而被嘲笑之后，博克洛夫（Boklöv）在1988-89年世界杯比赛和科学测试中获得第一名后，后来成为世界杯滑雪跳高运动员的模型，这证明了V型滑雪鞋具有出色的举升力。
The landing of a jump is made on a steep section of the hill in a more upright position, with the shock of contact taken up by the knees and hips and one ski farther forward than the other (the telemark position). After the slope levels off, the jumper stops his forward momentum by turning. In addition to the judges’ ability to lower the starting point, other precautions are taken to prevent overjumping, including limits on ski length and ski-suit thickness (thicker suits permit more air to be trapped in the suit and thereby allow for longer jumps) and rules for the placement of bindings on skis. The hills have also been altered for safety; hills are now contoured to ensure that a jumper is rarely more than 3 to 4.5 metres (10 to 15 feet) above the ground during a jump.
Competitors make two jumps. Performance is decided partly by distance covered and partly by form, on the basis of style marks awarded by five judges. Concerning distance, a jump to the K-point (where the distance from the starting point equals the height of the hill) garners a jumper 60 points, with additional points added for each metre beyond the K-point. Style points are deducted for such errors as touching the ground with a hand after landing or not landing with one foot before the other.
Ski flying is similar to ski jumping in every respect except its scoring system, which emphasizes distance over style. Under ideal conditions top contestants are capable of leaps of over 200 metres (656 feet). Ski flying is not included in the Olympics.
