Parliamentary elections were held in Poland on 15 October 2023 to elect members of the Sejm and Senate. A referendum containing four questions concerning economic and immigration policy of the government was held simultaneously.
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.
