Yellowstone County is the most populous county in the U.S. state of Montana. As of the 2020 census, the population was 164,731.[1] Its county seat is Billings,[2] 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.[3] The river, in turn, was named for the yellow sandstone cliffs in what is now Yellowstone County.[4]
Yellowstone County is included in the Billings, Montana Metropolitan Statistical Area.
