Whitetail is a small, unincorporated village in northern Daniels County, Montana, USA. The area was first used as a camp along a cattle-driving route in the 1880s. The town grew with the arrival of the Soo Line Railroad in 1914. The line was planned for extension all the way to Glacier National Park, but work was stopped during World War I and the line never went any farther than Whitetail.
