Freestyle skiing is a skiing discipline comprising aerials, moguls, cross, half-pipe, slopestyle and big air as part of the Winter Olympics. It can consist of a skier performing aerial flips and spins and can include skiers sliding rails and boxes on their skis. Known as "hot-dogging" in the early 1970s, it is also commonly referred to as freeskiing, jibbing, as well as many other names, around the world.

In 1969, Waterville Valley Ski Area in New Hampshire, formed the first freestyle instruction program, making the resort the birthplace of freestyle skiing. International Ski Federation (FIS) recognized freestyle skiing as a sport in 1979 and brought in new regulations regarding certification of athletes and jump techniques in an effort to curb the dangerous elements of the competitions.
