Gloydius strauchi is a venomous pitviper species endemic to western China. It is a small snake with a pattern of four longitudinal stripes, although some older specimens may be a uniform black. Gloydius strauchi may be distinguished from G. monticola by its higher midbody dorsal scale count. This species jointly holds the altitude record for pitvipers together with Crotalus triseriatus of Mexico, both being found even above the tree line at over 4,000 m (13,000 ft). No subspecies are currently recognized.
