1820–21 United States House of Representatives elections

The 1820–21 United States House of Representatives elections were held on various dates in various states between July 3, 1820, and August 10, 1821. Each state set its own date for its elections to the House of Representatives before the first session of the 17th United States Congress convened on December 3, 1821. They coincided with President James Monroe winning reelection unopposed.

In March 1820, seven House seats transferred from Massachusetts to Maine after the latter seceded from the former to become a separate state. The size of the House then increased to 187 seats after Missouri achieved statehood in 1821.

The virtually nonpartisan Era of Good Feelings, a period of national political dominance by the Democratic-Republican Party, continued. Despite small gains, the Federalist Party remained relegated to limited state and local influence.

Maine

This was the first election in Maine since its separation from Massachusetts. In the previous election, Massachusetts had had 20 representatives. Seven seats (representing the 14th-20th districts) were reassigned from Massachusetts to Maine. In addition, under the terms of the law which admitted Maine to the union, any vacancies in the 16th Congress by Representatives elected to represent Massachusetts but residing in the new states of Maine would be filled by a resident of Maine. John Holmes, who had been elected to the House for the former 14th district of Massachusetts was elected as one of the first two senators for Maine. The vacancy was filled in a special election by Joseph Dane (Federalist). Dane was the only Representative officially considered as representing Maine in the 16th Congress. The Representatives from the 15th-20th districts were still classified as being from Massachusetts for the remainder of the 16th Congress.

Maine elected its members on November 7, 1820. State law required a majority to win an election, necessitating additional ballots if a majority was not received. And, in fact, additional ballots were held on January 22, 1821, and September 10, 1821, after the term began but before the new Congress convened.

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 14th – 20th districts with it.

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

New York

New York elected its members April 24–26, 1821, after the term began but before the new Congress convened. The 21st district, previously a plural district with two seats, was divided into two single-member districts for the 17th Congress, the 21st and 22nd.

The Democratic-Republican party in New York was divided between "Bucktails" and "Clintonians". The Clintonians ran on a joint ticket with the remaining Federalists. In a few cases, marked as "Clintonian/Federalist" below, it is unclear whether a candidate on the joint ticket was Democratic-Republican or Federalist.

Only five of the twenty-seven incumbents were re-elected to the next term. Sixteen incumbents retired and five lost re-election. Despite this high turnover of membership, there was only a one-seat net gain for the Federalists.
