Steamboat Springs, known as Ski Town USA, is a town in Routt County, Colorado, United States. The population was 9,815 at the 2000 census. It is the county seat of Routt County. The town is an internationally known winter resort destination, highlighted by the Steamboat Ski Resort, which is on Mount Werner in the Park Range just east of the town. It also contains the much smaller Howelsen Ski Area. It is located in the upper valley of the Yampa River, along U.S. Highway 40 just west of the Continental Divide at Rabbit Ears Pass.

According to the United States Census Bureau, the city has a total area of 26.1 km² (10.1 mi²), all land. The Yampa Valley and surrounding area contain several geothermal hot springs. The city is named after the Steamboat Spring, located near the present day library, whose bubbling sounded like a steamboat to early white settlers. Unfortunately, blasting for the railroad in 1908 silenced the chugging spring. There are currently two springs in Steamboat that are open to the public. The largest is at the Steamboat Health and Rec Center, with multiple pools and a slide. A few miles out of town, up in the hills, is Strawberry Park Hot Springs, with two pools and complete darkness so you can relax under the stars. Clothing is optional after dark.
