Carrathool is a village in the western Riverina region of New South Wales, Australia, in Carrathool Shire. In 2011 census, Carrathool had a population of 296 people. It is about 5 kilometres (3 mi) north of the Sturt Highway between Darlington Point and Hay (on the opposite side of the Murrumbidgee River to the highway). The village is situated on the plain a few kilometres north of the river, clustered around the now-disused railway station.
The place name Carrathool is derived from the local Aboriginal word meaning "Native Companion".
