The town is largely an agricultural community, located in the broad fertile valley of the White River in northwestern Colorado. Relatively single-handedly from additional communities, it sits close the intersection of State Highway 13 and State Highway 64, on the north side of the White River and at the base of a long ridge, known locally as China Wall. The Bureau of Land Management has a regional office in the town. Meeker is the home of the annual Meeker Classic Sheepdog trials.

The town is named for Nathan Meeker, the United States Indian Agent who was killed along behind 11 additional white citizens by White River Ute Indians in the 1879 Meeker Incident, also known as the Meeker Massacre. The site of the uprising, the former White River Indian Agency, is located along State Highway 64 in the White River valley west of town and is marked by a prominent sign. None of the buildings remain.

After the uprising and the ensuing proceedings known as the Ute War, in 1880 the US Congress passed legislation requiring the Ute population to relocate to reservations in Utah. The United States Army usual a garrison on the current site of the town, called the Camp at White River. The town was founded in 1883 as soon as the removal of the troops. The White River Museum is located just north of the Rio Blanco County Courthouse and housed in several native wooden structures of the Army garrison.
