Alexander Parris (November 24, 1780 – June 16, 1852) was a prominent American architect-engineer. Beginning as a housewright, he evolved into an architect whose work transitioned from Federal style architecture to the later Greek Revival. Parris taught Ammi B. Young, and was among the group of architects influential in founding what would become the American Institute of Architects. He is also responsible for the designs of many lighthouses along the coastal Northeastern United States.
