Whitefish (Salish: epɫx̣ʷy̓u, "has whitefish") is a city in Flathead County, Montana, United States. The population was 6,357 at the 2010 census. It is home to a ski resort on Big Mountain called Whitefish Mountain Resort.
The Great Northern Railway was built through what is now Whitefish in 1904, which sparked development of the town. The area was originally known as Stumptown due to the abundant amount of timber that had to be cleared to build the town and railroad and because tree stumps were left in the streets throughout downtown. Early residents of the town worked for the railroad and nearby logging industries. By the late 1940s, with the successful construction of a ski resort on Big Mountain (a collaboration among local businessmen) the tourism sector was becoming increasingly important. The community was named for its location near Whitefish Lake.
In 2006, over 68,000 passengers embarked and disembarked through the historic Whitefish Depot, a stop on Amtrak's Empire Builder line, with some percentage of those being headed to the ski resort on Big Mountain.
