The Barnes House is a historic house at 183 Pine Street, Quincy, Massachusetts. The 2-1/2 story house was built in the 1870s, and is a fine local example of Italianate styling. It is three bays wide, with the first floor left bays taken up by a large projecting bay with four sash windows and a bracketed eave. The windows on the second floor have bracketed cornices, and the front entry is sheltered by a decorated porch with turned posts. The house is further distinctive because it has a surviving period barn/carriage house. The builder was probably Howard C. Barnes, who was in the musical instruments business.
