The Huntley Post Office was established in 1877, one mile upstream from present-day Huntley. It was a stage station and stopping-off place for freighters and travelers. It also served as head of steamboat navigation on the Yellowstone River. In 1882, the Northern Pacific Railroad built a section house and depot a mile east and on the opposite bank of the river, and the growth center of Huntley followed. Since the town was located in the project, the Huntley Irrigation Project name came naturally

The name ‘Huntley Project’ is short for Huntley Irrigation Project, which was the second U.S. Bureau of Reclamation irrigation project. The area was part of the Crow Indian Reservation from 1874 to 1904 when the government purchased the 35,000 acres, stretching across 27 miles from Huntley east to the Little Bull Mountains.
The irrigation headgates opened on the project July 22, 1907, and homesteading began.
