Waterman, also known as Waterman Flat, is an unincorporated community in Wheeler County, in the U.S. state of Oregon. Waterman lies southeast of Richmond and northeast of Mitchell at the intersection of Richmond Road, Parrish Creek Road, and Waterman Road. Waterman Road intersects U.S. Route 26 about south of Waterman. The cattle-ranching community had a post office from 1887 to 1944. Caleb N. Thornburg was the first postmaster. In the late 19th century, Waterman Flat was a stagecoach stop with a hotel and a livery stable. By 1975, the ruins of a barn were all that remained.
