Sumner, Oregon

Sumner is an unincorporated community in Coos County, Oregon, United States. It is about 10 mi southeast of Coos Bay on the route of the old Coos Bay Wagon Road.

According to William Gladstone Steel, the community was founded in 1888 by John B. Dalley (other sources have the spelling as "Dulley" ), who named it after Charles Sumner, a Massachusetts senator who died in 1874. Sumner post office was established in 1874, so according to Oregon Geographic Names, Steel must have been incorrect about the 1888 founding date. Dalley was the first postmaster, and the office closed in 1961. In 1915, Sumner had a population of 100. As of 1990, the community had one store.
