Vikersundbakken or Vikersund Hill is a ski flying hill at Vikersund in Modum, Norway. It is one of the two largest purpose-built ski flying hills in the world. Nine world records have been set there, including the current record of 253.5 meters, set by Stefan Kraft. The complex consists of a large hill, a normal hill and several training hills.

Ski flying is a winter sport discipline derived from ski jumping, in which much greater distances can be achieved. It is a form of competitive individual Nordic skiing where athletes descend at high speed along a specially designed takeoff ramp using skis only; jump from the end of it with as much power as they can generate; then glide – or 'fly' – as far as possible down a steeply sloped hill; and ultimately land within a target zone in a stable manner. Points are awarded for distance and stylistic merit by five judges. Events are governed by the International Ski Federation.
