Prime Minister's Questions (PMQs) (officially Questions to the Prime Minister) is a constitutional convention in the United Kingdom, where every Wednesday when the House of Commons is sitting the Prime Minister spends half an hour answering questions from Members of Parliament ("MPs").

In Canada, this convention is known as Question Period and occurs both in the federal Parliament and in the provincial legislatures. In Australia and New Zealand the period is called Question Time. In the Irish Dáil, the practice is called Leader's Questions. In the Scottish Parliament, Northern Ireland Assembly and National Assembly for Wales this practice is called First Minister's Questions. India's Lok Sabha has a Question Hour. In Israel, it has been recently suggested that such practice should commence in the Knesset twice a year.
