The Cals cabinet was the executive branch of the Dutch Government from 14 April 1965 until 22 November 1966. The cabinet was formed by the christian-democratic Catholic People's Party (KVP) and Anti-Revolutionary Party (ARP) and the social-democratic Labour Party (PvdA) after the fall of the previous Cabinet Marijnen. The cabinet was a Centre-left coalition and had a substantial majority in the House of Representatives; prominent Catholic politician Jo Cals, a former Minister of Education, served as Prime Minister. Labour Leader Anne Vondeling served as Deputy Prime Minister and Minister of Finance, Protestant Leader Barend Biesheuvel continued as Deputy Prime Minister, Minister of Agriculture and Fisheries and the responsibility for Suriname and Netherlands Antilles Affairs from previous cabinet.

The Catholic People's Party was a Catholic Christian democratic political party in the Netherlands. The party was founded in 1945 as a continuation of the interwar Roman Catholic State Party, which was in turn a successor of the General League of Roman Catholic Caucuses. The party was in government throughout its existence. In 1977, a federation of parties including the Catholic People's Party, the Anti-Revolutionary Party (ARP) and the Christian Historical Union (CHU) ran together under the Christian Democratic Appeal (CDA) banner. The three participating parties formally dissolved to form the CDA in 1980.
