Riley is an unincorporated community in Harney County, Oregon, United States, located at the crossroads of U.S. Highway 395 and U.S. Highway 20, milepost 104, about 28 miles (45 km) west of Burns, the seat of Harney County.

It exists to serve the rural farming and ranching community that surrounds it, and highway travelers.

[3][4] Previously, the nearest post office was at Hardin, 75 miles (121 km) northwest of Riley, so the people who lived along Silver Creek made Riley their new gathering spot.

[3] 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.

[6] In the 21st century, Riley is a stop on the Eastern POINT intercity bus line between Bend and Ontario.
