The South Fork Malheur River is a tributary of the Malheur River in a sparsely populated part of the U.S. state of Oregon. Arising southeast of the unincorporated community of New Princeton and slightly north of Oregon Route 78, it flows generally northeast to meet the Malheur near the unincorporated community of Riverside in Malheur County. The South Fork enters the larger river 96 miles (154 km) by water from its confluence with the Snake River.
