The 1822–23 United States House of Representatives elections were held on various dates in various states between July 1, 1822, and August 14, 1823. Each state set its own date for its elections to the House of Representatives before the first session of the 18th United States Congress convened on December 1, 1823. They occurred during President James Monroe's second term.
Following the congressional reapportionment based on the 1820 United States census, the House increased by 26 seats to a total of 213. Most relative population growth was in the West. This was the last House election during the virtually nonpartisan Era of Good Feelings and the largest midterm gain of seats by a President's party. The Democratic-Republican Party remained nationally dominant, and the Federalist Party was limited to state and local influence.
This election heralded key change not apparent until the end of the 18th Congress. The four-way 1824 presidential election, in which all candidates ran as Democratic-Republicans, would result in no candidate winning an Electoral College majority. Representatives elected to the 18th Congress are often classified by how they voted in the 1825 contingent election, which after a controversial, unanticipated political deal chose John Quincy Adams President, triggering a new, rancorous, abruptly realigned period of partisanship.
This election marked the second time in American history where the incumbent president's party gained House seats in a midterm election while still losing seats in the Senate, this happened before in 1814 and again in 1902.
Following the 1820 census, 26 new seats were apportioned, with 4 States losing 1 seat each, 9 States gaining between 1 and 8 seats, and the remaining 11 States having no change in apportionment.
There were special elections in 1822 and 1823 to the 17th United States Congress and 18th United States Congress.
Special elections are sorted by date then district.

Delaware was reduced once more from two back to one seat after the fourth census, which number has remained constant to the present day. At the time of the October 1, 1822, election, the second seat in Delaware's at-large district was vacant, so there was only one incumbent going into the election.

Indiana's single at-large seat in the 17th Congress was empty at the time of the election, previous incumbent William Hendricks (Democratic-Republican) having resigned to run for Governor of Indiana.

Although Maine neither gained nor lost seats after the 1820 United States census, redistricting placed two incumbents into the 3rd district. Maine elected its members April 7, 1823, after the term began but before the new Congress convened. Maine law required a majority for election, with additional ballots taken if a majority were not achieved. This proved necessary in 1822 in the 1st, 3rd, 4th, and 6th districts, but all members were still chosen before the new Congress convened.
Maryland elected its members October 7, 1822.
Massachusetts elected its members November 4, 1822. Massachusetts law required a majority for election, which was not met in 3 districts, necessitating additional elections on March 3, 1823, and May 12, 1823; nevertheless, all elections were complete before the new Congress convened.

New Hampshire elected its members August 26, 1822. New Hampshire law required a candidate to receive votes from a majority of voters for election, that is 1/12 of votes. Only five candidates received the requisite majority, and so a May 11, 1823, run-off election was held for the sixth seat.

As in the previous election, the Democratic-Republican Party in New York was divided into two factions, the "Bucktails" and the Clintonians, which distinction is not marked here. The Clintonians and the Federalists ran on a joint ticket in 1822 as in 1821, in some cases, it's unclear which party a candidate belonged to, those are marked Crawford Federalist.
