Benjamin Adams (born December 16, 1764) was a Federalist politician who represented the Commonwealth of Massachusetts in the United States House of Representatives in the early nineteenth century. Serving as a member of the U.S. House from December 4, 1815, to March 3, 1821, he held office during a formative period in the nation’s political development, when the Federalist Party was nearing the end of its influence in national affairs.

Adams represented Massachusetts’s 11th Congressional District and completed three terms in Congress. As a Representative, he was part of the Federalist delegation from Massachusetts, reflecting the party’s continued strength in New England during his years in office. His service concluded in 1821, and he is recorded as a former member of Congress, with no additional official roles or committee assignments noted in the available record.
