Callambulyx tatarinovii or unmonsuzume (ウンモンスズメ) in Japanese is a species of moth of the Sphingidae family. It is found from northern Xinjiang across northern China, Mongolia, southern Siberia to the Russian Far East and Japan, and then south through Korea and central China to eastern Tibet. It is also found in Taiwan.

The wingspan is 56–82 mm. It is very similar to Smerinthus kindermannii, but the forewing colours are predominantly green and grey although there is a northern form in which all green coloration is replaced by brown.
There are one to two generations per year in China. In Korea, adults are on wing from early May to mid October.
The larvae have been recorded feeding on Ulmus parvifolius in Guangdong and Zelkova in northern China. Other recorded foodplants in China include Euonymus alatus, Salix, Populus and Prunus persica, but these require confirmation. In Korea, recorded hostplants include Ulmus davidiana var. japonica, Zelkova serrata, Tilia amurensis and Euonymus sieboldianus, while Ulmus japonica is recorded for the Russian Far East. Subspecies gabyae has been recorded feeding on Zelkova serrata.
