The Beaverton Downtown Historic District comprises a primarily commercial and civic portion of downtown Beaverton, Oregon, United States. Beaverton's historic commercial core remains largely intact as a pedestrian-oriented business district constructed along the street pattern from the city's earliest plats. Significant buildings include a handful from the city's first decades (1868–1920) and a larger number from the period of profound transformation between the world wars (1920–1940). The district was listed on the National Register of Historic Places in 1986.
