The First National Bank Building is a building located in downtown Portland, Oregon, listed on the National Register of Historic Places.

[3] Located at 401–409 SW 5th Avenue, designed by Coolidge and Shattuck of Boston, resembling some of the Lincoln Memorial classicism, it was built in 1916 when the bank outgrew its earlier quarters and when it was subsequently under the ownership of H.W.

The bank's design bred confidence and was a symbol of security.

[5] The original building of 1916 continued to form part of the two-building headquarters complex until 1972, when First National moved its headquarters to the new 40-story tower adjacent to the administration services building next to City Hall.

[6][7] The building was saved from destruction and given an historical landmark designation by the city.
