Riley, Oregon is an unincorporated community in Harney County, Oregon, United States. The center of the community is at the crossroads of U.S. Highway 395 and U.S. Highway 20, milepost 104. Riley is about 28 miles (45 km) west of Burns, the seat of Harney County. The elevation of Riley is 4,226 feet (1,288 m).
A post office named Riley was established in about 1885, and named for stockman Amos Riley of the ranching partnership Riley and Hardin. There was a Hardin post office located 75 miles (121 km) northwest of Riley, so the people who lived on Silver Creek suggested the new post office be called Riley. Riley's post office closed in 1919, but was reopened in 1949 after an office called Suntex was closed.
The Oregon Department of Transportation has a camera for road and weather conditions located at the intersection of U.S. 20 and U.S. 395 in Riley, facing west-northwest.
