Hay, town, south-central New South Wales, Australia. It lies on the Murrumbidgee River.
The settlement originated in 1840 as a coach station known as Lang’s Crossing Place. It was surveyed in 1858 and became a town the following year, named for John Hay, a district parliamentary representative. Developed as a river port, it was proclaimed a municipality in 1872 and a shire in 1965. Hay is situated at the junction of the Sturt, Cobb, and Mid Western highways and forms the terminus of a rail line from Sydney (some 370 miles [600 km] northeast). It now serves a wide area (of the far-western Riverina) of semiarid grazing and irrigated-fruit and dairy farming. Pop. (2006) local government area, 3,383; (2011) local government area, 2,956.
