Agrarian socialism is a political ideology that promotes social ownership of agrarian and agricultural production as opposed to private ownership. Agrarian socialism involves equally distributing agricultural land among collectivized peasant villages. Many agrarian socialist movements have tended to be rural, locally focused, and traditional. Governments and political parties seeking agrarian socialist policies have existed throughout the world, in regions including Europe, Asia, North America, Latin America, and Africa.

Agrarianism is a social and political philosophy that promotes subsistence agriculture, family farming, widespread property ownership, and political decentralization. Adherents of agrarianism tend to value traditional bonds of local community over urban modernity. Agrarian political parties sometimes aim to support the rights and sustainability of small farmers and poor peasants against the wealthy in society.
