Leiocassis is a genus of bagrid catfishes found mostly in Southeast Asia with some species occurring in China.

This genus has a confused taxonomy and there is uncertainty surrounding the number of valid species.^[2] Certain East Asian bagrids formerly placed in this genus have been moved to Pseudobagrus.^[2] In 2006, Heok Hee Ng considered the genus Leiocassis to be restricted to Sundaic Southeast Asia and Borneo and only a handful of species as valid (L. aculeatus, L. collinus, L. hosii, L. micropogon, L. poecilopterus, and L. tenebricus).^[2]

The members of Leiocassis have an elongate narrow head and a prominently protruding snout.^[2]
