The taiga shrew's range extends from Fennoscandia in the west, through northern and central Russia, north Mongolia and northern China, and northern Kazakhstan, to the Pacific coast and Sakhalin island. In Europe, it is more or less continuously distributed from Finland to northern Russia and northern Belarus (Corbet 1978, Sulkava 1999). Populations in Norway and Sweden may be isolated; the species was not detected in Fennoscandia until as late as 1949 (Sulkava 1999). In Mongolia, occurs along the Sögnögör River in south-western Hentii Mountain Range, and in Züünbürkh in eastern Hentii Mountain Range (Shvetsov et al., 1980); also occurs in parts of Mongol Daguur Steppe. In China, distribution is restricted to the northeastern regions of Heilongjiang and E Nei Mongol.
