Line Skis, commonly shortened to Line or stylized as LINE, is a new school skis company owned by K2 Sports. Line Skis was founded by Jason Levinthal in 1995 to produce short, twin-tipped skis for freestyle skiers, and has since moved to produce full-length free skis.

Freeskiing, or new school skiing, is a specific type of alpine skiing, which involves tricks, jumps, and terrain park features, such as rails, boxes, jibs, or other obstacles. This form of skiing resulted from the growth of snowboarding combined with the progression of freestyle skiing. "Newschoolers", or those who specifically ski in this style, as opposed to traditional freestylers, freeriders, big mountain skiers, and racers, are often found in terrain parks, which are designed specifically for tricks.
