The 2023 Louisiana State Senate election was held on October 14, 2023, with runoff elections held on November 18, 2023.[1] All 39 seats in the Louisiana State Senate were up for election to four-year terms. It was held concurrently with elections for all statewide offices and the Louisiana House of Representatives.
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.
In the 2019 state legislature elections, Republicans expanded their majorities in both chambers to 68 in the House and 27 in the Senate.[2] [3] Going into the 2023 elections, Republicans held a two-thirds supermajority in both the Senate and the House.
The 2023 election was the first election held under new district maps following redistricting as a result of the 2020 census.[4]
