The Cresta Run is a natural ice skeleton racing toboggan track in eastern Switzerland. Located in the winter sports town of St. Moritz, the 1.2125 km (0.753 mi) run is one of the few in the world dedicated entirely to skeleton. It was built in 1884.

The Cresta Run was founded by devotees of sledding (tobogganing in British parlance) who adopted a head-first (prone) technique of racing down an icy run, as opposed to the feet-first (supine) and somewhat faster luge race. Both evolving sports were natural extensions of the invention of steerable sleds during the early 1870's. These initial crude sleds were developed almost accidentally — as bored well-to-do gentlemen naturally took to intramural competition in the streets and byways of twisty mountainous downtown roadways hazarding each other and pedestrians alike. This gave impetus to a desire to steer the sleds, and soon runners and a clumsy mechanism evolved to allow that ability.

The run's head (top) is located under the remains of a Twelfth-century church, torn down in 1890, known as the 'Leaning Tower'. The overall drop is 157 m (515 ft) and the gradient varies from 2.8 to 1 to 8.7 to 1 (length to drop). The track served as host of the skeleton event for both the 1928 and the 1948 Winter Olympics. These were the only Olympics with skeleton until 2002.

Current rules forbid women riders, but towards the end of the season there is a Ladies Event in which women compete by invitation only.
