The Dean House is a historic house at 1520 Beech Street in Texarkana, Arkansas. It is a two-story wood-frame house, built in 1911 for Thomas Mercer Dean, a local farmer and lumberman. Its principal distinguishing feature is its large Colonial Revival portico, with paired two-story Tuscan columns supporting an elaborate entablature. Porches wrap around the north and east sides of the house, and there is a porte-cochère at the southern corner.[2]
