Brandt's ground squirrel is found from the Lake Zaysan region in eastern Kazakhstan, southwards and westwards along the Tian Shan mountain range to the vicinity of Almaty, on both sides of the Kazakh-Chinese border. The closely related species, Spermophilus alashanicus from the Alashan Desert and Spermophilus pallidicauda, found in north east Gansu and Inner Mongolia, are allopatric in distribution, separated as they are by geographic boundaries.
