2023 Louisiana House of Representatives election

The 2023 Louisiana House of Representatives election was held on October 14, 2023, with runoff elections held on November 18, 2023. All 105 seats in the Louisiana House of Representatives were up for election to four-year terms. It was held concurrently with elections for all statewide offices and the Louisiana State Senate.

Under Louisiana's jungle primary system, all candidates appear on the same ballot, regardless of party, and voters may vote for any candidate, regardless of their party affiliation.

Background
In the 2019 state legislature elections, Republicans expanded their majorities in both chambers to 68 in the House and 27 in the Senate. They had a supermajority of 71 members in the House, after elected Democrats Malinda White, Francis C. Thompson and Jeremy LaCombe switched parties.

In the 2020 Presidential Election, Republican Donald Trump won 72 Louisiana House of Representatives districts and Democrat Joe Biden won 33 districts. Going into the 2023 Louisiana State House Elections, Democrats represented two districts where Trump won the most votes in 2020: District 60, located in rural Louisiana (Trump +9%) and District 105, located primarily in Plaquemines Parish (Trump + 6%). Going into the 2023 elections, Republicans represented one district where Biden won the most votes in 2020: District 92, in the New Orleans suburbs of Jefferson County ( Biden + 8%). In addition, the Independent Joseph Marino had represented District 85, which Biden won by 8%, before he resigned in 2023. The 2023 election was the first election held under new district maps following redistricting as a result of the 2020 census.

Special elections
One special election was held on February 18, 2023, with a runoff on March 25, 2023, to fill a vacancy in District 93. Incumbent Democrat Royce Duplessis resigned on December 6, 2022, to join the State Senate. Democrat Alonzo Knox won this election.
