It borders Mendoza Province to the north, Rio Negro Province to the southeast, and Chile to the west. It also meets La Pampa Province at its northeast corner. The Neuquén Province receives its name from the Neuquén River. The term "Neuquén" derives from the Mapudungun word "Nehuenken" meaning drafty, which the aborigines used to refer to this river. The word, without accentuation, is a palindrome.
