The Dutch States Party was a political faction of the United Provinces of the Netherlands. This republican faction is usually (negatively) defined as the opponents of the Orangist, or Prinsgezinde faction, who supported the monarchical aspirations of the stadtholders, who were usually members of the House of Orange-Nassau. The two factions existed during the entire history of the Republic since the Twelve Years' Truce, be it that the role of "usual opposition party" of the States Party was taken over by the Patriots after the Orangist revolution of 1747. The States Party was in the ascendancy during the First Stadtholderless Period and the Second Stadtholderless Period.

In the history of the Dutch Republic, Orangism or prinsgezindheid was a political force opposing the Staatsgezinde (pro-Republic) party. Orangists supported the Princes of Orange as Stadtholders and military commanders of the Republic, as a check on the power of the regenten. The Orangist party drew its adherents largely from traditionalists – mostly farmers, soldiers, noblemen and orthodox Protestant preachers, though its support fluctuated heavily over the course of the Republic's history and there were never clear-cut socioeconomic divisions.
