The Riverina () is a large farming area in the south west of New South Wales, Australia. It has flat plains, warm to hot climate and a large supply of water for irrigation. This has allowed the Riverina to become one of the most productive and agriculturally varied areas of Australia. With the state of Victoria to the south, and the mountains of the Great Dividing Range to the east, the Riverina covers those areas of New South Wales in the Murray and Murrumbidgee river systems.
