A referendum was held in Poland on 15 October 2023, taking place alongside the nationwide elections to the Senate and Sejm.

Voters were asked whether they approve of the privatisation of state-owned enterprises, an increase in the retirement age, the admission of immigrants under the EU relocation mechanism, and the removal of the barrier on Poland's border with Belarus.

[3][4][5] The referendum was boycotted by the main opposition parties resulting in a turnout of only 40%[6] (compared to more than 70% for the election[7]).

[11] The ruling Law and Justice party was accused of inciting anti-immigrant sentiment to boost turnout among its voters on election day.

[12] The law had been changed shortly before the announcement of the referendum to allow it to be held on the same day as the parliamentary election, which was referred to as a way to skirt past electoral campaign budget limits by the incumbent Law and Justice party under the false pretense of referendum funding.
