Parliamentary elections were held in Poland in 1989 to elect members of the Sejm and the recreated Senate. They were the first free elections in the country since 1928, and the first since the communist Polish United Workers Party abandoned its monopoly of power in April 1989.

Not all parliamentary seats were contested, but the resounding victory of the Solidarity opposition in the freely contested races paved the way to the fall of Communism in Poland. Solidarity won all of the freely contested seats in the Sejm, and all but one seat in the entirely freely contested Senate. In the aftermath of the elections, Poland became the first country of the Eastern Bloc in which democratically elected representatives gained real power. Although the elections were not entirely democratic, they led to the formation of a government led by Tadeusz Mazowiecki and a peaceful transition to democracy in Poland and elsewhere in Central and Eastern Europe.
