A special election was held in Maine's 1st congressional district on November 7, 1820 to fill a vacancy left by the resignation of John Holmes. Holmes had been elected under the authority of the State of Massachusetts to that state's former 14th district, part of the District of Maine. When, on March 15, 1820, the former District was granted statehood as the State of Maine, Holmes was elected one of its first two Senators. Under the act admitting Maine as a state, seven seats were moved from Massachusetts to Maine for the 17th Congress, and any vacancies in the 16th Congress that arose in seats held by residents of Maine were to be filled by residents of the new state.
The special election was held on the same date as the general elections for the 17th Congress.
