The Martin House is a historic residence in the Mount Washington neighborhood of Cincinnati, Ohio, United States. Built in 1847, the house is composed of two pieces: the original section, located in the back; and the front, built in 1852. Between the two components, it features elements of the Greek Revival and Federal architectural styles. Built of brick, two stories tall, it was originally a farmhouse belonging to John C. Martin, who built his home on property owned by his father-in-law Ezekiel Rigdon, who owned nearly 100 acres (40 ha) of land on Mount Washington near the farm of one of the area's first settlers.
