The Reformed Political Party is a conservative Calvinist political party in the Netherlands. The term Reformed is not a reference to political reform but is a synonym for Calvinism—a major branch of Protestantism. The SGP is the oldest political party in the Netherlands existing in its present form, and has been in opposition for its entire existence. Since 1925, it has won between 1.6% and 2.5% of the votes in general elections. Owing to its orthodox political ideals and its traditional role in the opposition, the party has been called a testimonial party. Since the general election of 2012, it has held three of the 150 seats of the House of Representatives.

Early general elections were held in the Netherlands on 12 September 2012 after Prime Minister Mark Rutte handed in his government's resignation to Queen Beatrix on 23 April. The 150 seats of the House of Representatives were contested using party-list proportional representation. The People's Party for Freedom and Democracy (VVD) received a plurality of the votes, followed by the Labour Party (PvdA).
