Ski cross is a skiing competition which incorporates terrain features traditionally found in freestyle skiing with courses which include big-air jumps and high-banked turns. In spite of the fact that it is a timed racing event, it is often considered a type of freestyle skiing. What sets ski cross apart from other alpine skiing disciplines is that it involves more than one skier racing down the course. Any intentional contact with other competitors like grabbing or any other forms of contact meant to give the competitor an advantage leads to disqualification.

Skiing is the use of skis to glide on snow. Variations of purpose include basic transport, a recreational activity, or a competitive winter sport. Many types of competitive skiing events are recognized by the International Olympic Committee (IOC), and the International Ski and Snowboard Federation (FIS).
