Victor Gerard Marie Marijnen was a Dutch politician of the Catholic People's Party (KVP) and jurist who served as Prime Minister of the Netherlands from 24 July 1963 until 14 April 1965.

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.
