The Populist Party was a political party in the United States between 1984 and 1996. It was conservative and often white nationalist in its ideology. The party was unrelated to the original American Populist Party or other American parties that have used the same name. Willis Carto helped found the Populist Party, which eventually served as an electoral vehicle for the former Knights of the Ku Klux Klan leader, David Duke. The party was also known as the "America First" party.

The People's Party, also known as the Populist Party or simply the Populists, was an agrarian populist political party in the United States in the late 19th century. The Populist Party emerged in the early 1890s as an important force in the Southern and Western United States, but collapsed after it nominated Democrat William Jennings Bryan in the 1896 United States presidential election. A rump faction of the party continued to operate into the first decade of the 20th century, but never matched the popularity of the party in the early 1890s.
