The Subashi Formation () is a Late Cretaceous (Campanian to Maastrichtian)Xi et al., 2018 formation from the Xinjiang Autonomous Region of western China.Subashi Formation at Fossilworks.org Initially described by Dong Zhiming in 1977, the formation contains remains of Tarbosaurus which were initially described as a separate taxon Shanshanosaurus huoyanshanensis. Remains of a sauropod, likely Nemegtosaurus, and a hadrosaurid, likely Jaxartosaurus, have also been found.
The formation is located in the Flaming Mountains region of Xinjiang, north of the Turpan Depression. It is not far from Lianmuqin Town of Shanshan County,Glut, 2001 and is presumably named after the village of Subashi (), which is located some to the west of Lianmuqin, in Tuyugou Township (吐峪沟乡).
