The DeRosay-McNamee House is an historic house at 50 Mt. Vernon Street in Cambridge, Massachusetts. It is a 2-1/2 story brick house, with a dormered hip roof and limestone trim. Its main facade exhibits high-quality Colonial Revival styling, with a symmetrical appearance that includes rounded bays flanking the main entry, and an entrance porch supported by clusters of distinctively turned columns. It was built c. 1895-6 by the principal owner of a local brickyard, who pioneered modernizations allowing for the year-round manufacture of bricks.
