Huntley is a census-designated place (CDP) in Yellowstone County, Montana, United States. The population was 411 at the 2000 census. Huntley lent its name to the Huntley Project, a federal irrigation project that began delivering water to the arid district in 1907. Today, Huntley is an eastern suburb of Billings and is located east of Shepherd and west of Worden.

Yellowstone County is the most populous county in the U.S. state of Montana. As of the 2020 census, the population was 164,731. Its county seat is Billings, the state's most populous city. Like the nearby park, Yellowstone County is named after the Yellowstone River which roughly bisects the county, flowing southwest to northeast. The river, in turn, was named for the yellow sandstone cliffs in what is now Yellowstone County.
