Orange Farm ("Farma") is a township located approximately 45 km (28 mi) from Johannesburg in the Gauteng Province of South Africa. It is the southernmost township of the City of Johannesburg Metropolitan Municipality. Its name, a misnomer given that oranges are grown in orchards instead of farms, has Dutch origins. It is one of the youngest townships in South Africa, with the original inhabitants, laid-off farm workers, taking up residency in 1988. Support for the population came slowly mostly from people who were tenants at the larger township of Soweto.

In South Africa, the terms township and location usually refers to an underdeveloped racially segregated urban area, from the late 19th century until the end of apartheid, were reserved for non-whites, namely Black Africans, Coloureds and Indians. Townships were usually built on the periphery of towns and cities. The term township also has a distinct legal meaning in South Africa's system of land title, which carries no racial connotations.
