Pittsburg is an unincorporated community in Columbia County, Oregon, United States. Pittsburg is located on the Nehalem River near its confluence with the East Fork Nehalem River. The Scappose-Vernonia road and the St. Helens-Pittsburg road join Oregon Route 47 near Pittsburg.[2] Pittsburg's elevation is 584 feet (178 m).[1]

Pittsburg was named by early area resident Peter Brous, who settled there in 1879 and built a sawmill and a gristmill.[3] Brous named the community for Pittsburgh, Pennsylvania, having formerly lived in that state.[3] The Oregon post office was established with the name "Pittsburgh" on April 17, 1879, with Brous as the postmaster.[3] The name was changed to "Pittsburg" in 1892 and the post office was discontinued in 1908.[3]
