Franciscus Henricus Johannes Joseph "Frans" Andriessen was a Dutch politician of the defunct Catholic People's Party (KVP) and later the Christian Democratic Appeal (CDA) party and businessperson who served as European Commissioner from 6 January 1981 until 6 January 1993.

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.
