The National Party of Poland (SN) was a Polish nationalist political party that existed from 7 October 1928 to 1947, briefly being reactivated from 1989 to 1992. The party evolved from the Popular National Union (ZLN) party and opposed Jozef Pilsudski's totalitarian regime alongside several other right-wing parties, and the party had 200,000 members before the outbreak of World War II in 1939. The party sought to construct a Catholic Polish state by combining the principles of Catholicism and nationalism, and the organization was outlawed in Poland after the proclamation of the Polish People's Republic, operating in exile in London. In 1989, with the fall of communism in Poland, the party was reactivated in the homeland, and it was officially reactivated on 27 August 1990. In 1992, the party underwent splits, weakening the small party even more.
