The Aaron Hill House is a historic house at 17 Brown Street in Cambridge, Massachusetts. It was built c. 1754, and was originally a two-story structure with a steeply pitched roof. It was moved c. 1867 from its original location at 99 Brattle Street, at which time the third story was added, giving the roof a gambrel shape. The house was built for Deacon Aaron Hill, a prominent local politician, and is one of only seven houses from that period that still stands in the city.
