Billings, city, seat (1883) of Yellowstone county, south-central Montana, U.S., on the Yellowstone River 3,119 feet (951 metres) above sea level. Billings lies at the base of the Rimrock Mountains in the Clark’s Fork Bottom at a point equidistant from Seattle, Washington, and St. Paul, Minnesota.
Bannack Indians, the first known inhabitants of the area now encompassing the city of Billings, were driven away by the Crow; a Crow reservation now lies southeast of the city. Lewis and Clark passed through in 1805–06, naming the site now known as Pompey’s Pillar for the infant son of the their guide Sacagawea, whom Clark nicknamed Pomp, or Pompey. A site called Coulson—consisting of a trading post and stagecoach station—was settled in 1877, but in 1882, when the area was surveyed by Northern Pacific Railway Company, the city was renamed for a president of the railroad, Frederick Billings. Prosperity, spurred by the railroad’s arrival, collapsed after 1887 but was renewed after 1900 with the growing cattle industry and irrigated agriculture.
Billings is the metropolis of the “Midland Empire,” a rangeland and irrigated river valley region producing sugar beets and varied truck crops, wool, and livestock. Beet sugar, oil refining, and food processing are important. The city serves as a gateway to Yellowstone National Park and the Little Bighorn Battlefield National Monument. It is home to Montana State University-Billings, founded as a normal school (teachers college) in 1927, and to Rocky Mountain College (1898). ZooMontana, a zoological garden housing native and exotic animal species, is a popular attraction. Yellowstone, Glacier, and Grand Teton national parks are nearby. Pictograph Cave State Monument, 7 miles (11 km) southeast, has prehistoric artifacts. Inc. 1885. Pop. (2010) 104,170; Billings Metro Area, 158,050; (2020) 117,116; Billings Metro Area, 184,167.
