The United States National Bank Building in downtown Portland, Oregon was designed by A. E. Doyle in a Roman classical style, and is listed on the National Register of Historic Places. The four-story building's first section, facing Sixth Avenue, was completed and opened in 1917. The building features a four-story Corinthian colonnade at its eastern end (originally the principal façade) and makes extensive use of glazed terracotta. The interior is also decorated extensively with highly textured materials.

The building was constructed for the United States National Bank of Portland (USNB), which ultimately became part of U.S. Bancorp, whose retail banking division operates as U.S. Bank. An extension westward to Broadway was added in 1925, approximately doubling the building's size such that it now occupies half a city block. It continues to serve as the bank's main branch in the city.
