Whitehall was named after a large white ranch home, owned originally by E. G. Brooke. It was used as a stopping place for stages running from Helena to Virginia City. Brooke named his structure "Old Whitehall" after a similar structure in Whitehall, Illinois. The original station and post office is located 4 miles from where Whitehall now stands. The community began to develop after the railroad came through in 1889.

The only physical evidence of the Lewis and Clark Expedition is Captain William Clark's signature at Pompeys Pillar. Almost 200 years later the town of Whitehall is leaving its own mark of the upcoming Lewis and Clark Bicentennial on downtown buildings. Brightly colored murals depict actual events that members of the expedition experienced as they passed through this area during their 1803 - 1806 journey.
