Sod House Ranch, Historic ranch site in Harney County, Oregon, United States

Sod House Ranch is a historic ranch complex in Harney County, Oregon, with eight remaining buildings. It lies south of Malheur Lake in the Malheur National Wildlife Refuge, near the mouth of the Donner und Blitzen River. The buildings are listed on the National Register of Historic Places.

Peter French bought the 43,000-acre Sod House Ranch from A. H. Robie in 1877 and made it the northern division headquarters of the French-Glenn Livestock Company. After French was shot dead by a settler near the ranch on December 26, 1897, the company sold off its land. The U.S. government bought the property in 1935 to add to the adjacent wildlife refuge.

The name comes from the sod house built at this northern division of the French-Glenn Livestock Company, near the mouth of the Donner und Blitzen River. Peter French ran cattle here from the 1880s until his murder in 1897; the company sold the property in 1906 to Henry L. Corbett and C. E. S. Wood.

The ranch is accessible through the Malheur National Wildlife Refuge, where guided tours explain the construction and ranch operations. Visitors should prepare for open terrain and variable weather in this remote location.

Peter French was shot dead on December 26, 1897, near the Sod House Ranch by a settler who had been denied a road easement across his land. The ranch served as the northern division headquarters of the French-Glenn Livestock Company, which at its height ran 30,000 to 45,000 cattle and 3,000 horses and mules behind 500 miles of barbed wire fence.
