Alexander Contee Hanson (born February 27, 1786) was a Federalist politician who represented the state of Maryland in the United States Senate in the early nineteenth century. A member of the Federalist Party, he served as a senator from May 24, 1813, to April 23, 1819, during a period marked by the War of 1812 and its aftermath. His tenure placed him among the historical members of Congress from Maryland in the post-Revolutionary, early national era.

Hanson’s service in the Senate encompassed three terms as recorded in the available metadata, all in the capacity of a United States Senator for Maryland. Identified in congressional records by the bioguide ID H000176, he is noted specifically for his role as a Federalist senator rather than for committee assignments or additional offices, which are not documented here. After leaving office in 1819, he is remembered primarily for his contribution to Maryland’s representation in the Senate during a formative period in U.S. political history.
