The National Party of Australia, also known as The Nationals or The Nats, is a centre-right, agrarian political party in Australia. Traditionally representing graziers, farmers, and regional voters generally, it began as the Australian Country Party in 1920 at a federal level.

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.
