Monroe State Bank Building

The Monroe State Bank Building, located in Monroe, Oregon, is a building listed on the National Register of Historic Places. When it opened in 1911 it was headquarters of the only bank established in southeast Benton County, Oregon.

It is a two-story building which "dominates" Monroe's business district from its corner of South Fifth and Commercial streets. The building is approximately 26 x in plan.

This building has served as the telephone company and also as the home of the South Benton County Community Museum.

In 1992 the building was vacant and restoration was planned.
