A jackaroo is a young man working on a sheep or cattle station to gain practical experience in the skills needed to become an owner, overseer, manager, etc. The word originated in Queensland, Australia, in the 19th century and is still in use in Australia and New Zealand in the 21st century. Its origins are unclear, although it is firmly rooted in Australian English, Australian culture and in the traditions of the Australian stockmen.

In Australia, a station is a large landholding used for producing livestock, predominantly cattle or sheep, that needs an extensive range of grazing land. The owner of a station is called a pastoralist or a grazier, corresponding to the North American term "rancher".
