Hemibagrus is a genus of catfishes (order Siluriformes) of the family Bagridae.

The genus Hemibagrus is known from Southeast Asia, India, and southern China.[1] Members of this genus are found ubiquitously in river drainages east of the Ganges-Brahmaputra basin and south of the Yangtze basin, and reach their greatest diversity in Sundaland.[2]

This genus consists of large-sized catfishes.[2] H. wyckioides is the largest Bagrid catfish in central Indochina and may reach 80 kilograms.[3] It includes species with depressed (flattened) heads, rugose (ridged or wrinkled) head shields not covered by skin, and moderately long adipose fins.[2]

In Southeast Asia, Hemibagrus species are an important source of animal protein.[3]

The extinct species, H. major,[4][5] is a fossil species from a Miocene lake fauna from what is now Ban Nong Pia, Phetchabun Province of Thailand.

There are currently 41 recognized species in this genus:[6][7]
