The Oregon Theatre, or Oregon Theater, is an adult movie theater in the Richmond neighborhood of southeast Portland, Oregon. The theater was completed in 1925 and originally housed a Wurlitzer pipe organ and vaudeville stage. It would later screen Hollywood, art-house, and Spanish-language films. The building was acquired by the Maizels family in 1967 and became an adult cinema in the 1970s. It continues to operate as the city's longest running pornographic cinema and remains owned by a member of the Maizels family.
