Hemiprotosuchus is an extinct genus of protosuchid crocodyliform from the Late Triassic (Norian stage) Los Colorados Formation of the Ischigualasto-Villa Unión Basin in northwestern Argentina, South America.

Hemiprotosuchus was named by Argentinian paleontologist José Bonaparte in 1969.

[1] The fossils included a skull and jaws as well as some postcranial elements.

[2] A 2009 cladistic analysis of protosuchids by paleontologist Eric Buffetaut et al. found that Hemiprotosuchus was the sister taxon of Protosuchus.
