1820–1821 United States House of Representatives elections in Massachusetts

This was the first election in Massachusetts after the separation of the former District of Maine as the new State of Maine, taking the old MA's 14th congressional district – MA's 20th congressional district districts with it.

Massachusetts elected its members November 6, 1820. Massachusetts had a majority requirement for election, which was not met in the MA's 2nd congressional district necessitating two additional elections on January 8, 1821, and April 16, 1821, after the term began but before the new Congress convened.
