Mystus is a genus of small to medium-sized bagrid catfishes that occur in South and Southeast Asia.^[1]

Mystus is poorly diagnosed. Macrones had previously been used by earlier authors, but this generic name was preoccupied in Coleoptera.^[2] Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.^[3] It was confirmed in 2005 that this genus is paraphyletic.^[3]

There are two fossil species assigned to this genus both from the early Tertiary of the Sanshui Basin in Guangdong, China:

• Mystus spinipectoralis Li & Wang 1979
• Mystus dalungshanensis Li & Wang 1979
