The Peasants' Party was a political party in post-World War I Romania that espoused a left-wing ideology partly connected with Agrarianism and Populism, and aimed to represent the interests of the Romanian peasantry. Through many of its leaders, the party was connected with Poporanism, a cultural and political trend in turn influenced by Narodnik ideas. In 1926, it united with the Romanian National Party to form the National Peasants' Party (PNȚ).

The Narodniks were members of a movement of the Russian Empire intelligentsia in the 1860s and 1870s, some of whom became involved in revolutionary agitation against tsarism. Their ideology, known as Narodism, Narodnism or Narodnichestvo, was a form of agrarian socialism, though it is often misunderstood as populism.
