In Argentina, this species inhabits the western semiarid region of the country, from the Andean spurs (ca. 69ºW) to meridian 66ºW. South from the Río Grande, the distribution of the fox widens reaching the Atlantic coast. In Chile, it is present throughout the country. Its presence in Peru has been mentioned; to date, however, there has been no confirmation of it. The South American gray fox was introduced to the Falkland Islands in the late 1920s early 1930s and is still present in quite large numbers on Beaver and Weddell Islands plus several smaller islands.
