Eight of the country's 99 state legislative chambers held regularly-scheduled elections in 2023. Elections in those eight chambers represented 578 of the country's 7,386 state legislative seats (7.8%). This was the most seats up for election in an odd-numbered year since 2011.

General elections in Mississippi, New Jersey, and Virginia took place on November 7, 2023. General elections in Louisiana took place on November 18, 2023.

  • Democrats gained one state legislative chamber by winning partisan control of the Virginia House of Delegates. Democrats maintained control of the state Senate. Virginia's trifecta status remained divided.
  • Republicans were guaranteed simple majorities in both Mississippi's House and Senate and Louisiana's House and Senate due to the number of districts where candidates from only one political party ran.
  • Democrats maintained partisan control of both chambers of the New Jersey state legislature.
