2023 Polish parliamentary election

The 2023 Polish parliamentary election took place on Sunday, 15 October 2023, per the Polish Constitution. Seats in both the lower house, the Sejm, and the Senate were contested. At the polls, a referendum - containing four questions concerning economic and immigration policy of the government - was also voted on.

In the previous 2019 Polish parliamentary election, the ruling right-wing Law and Justice Party (PiS) had held onto its majority in the Sejm with Prime Minister Mateusz Morawiecki forming a second government. The PiS sought to win a third term which would be unprecedented in Polish history. The opposition, including the Civic Platform Party and others, secured a Senate majority. In the lead-up to the 2023 elections, opposition leader and former prime minister, Donald Tusk, led the Civic Coalition political alliance in opposition to the PiS.

The United Right alliance placed first for the third straight election and won a plurality of seats but fell short of a Sejm majority. The opposition, consisting of the Civic Coalition, Third Way, and The Left, achieved a combined total vote of 54%, managing to form a majority coalition government. In the Senate, the opposition electoral alliance Senate Pact 2023 won a plurality of the vote and a majority of seats. Voter turnout was 74.4%, the highest in contested elections and the highest since the fall of the communist Polish People's Republic, beating previous records set in 1989 and 2019.
