Comahuesuchus is an extinct genus of notosuchian crocodylomorphs from the late Cretaceous of Argentina.

The type species is C. brachybuccalis from the Santonian Bajo de la Carpa Formation.

Comahuesuchus is the name-sake of the clade Comahuesuchidae.

Sereno et al. (2003) suggested that Comahuesuchus and Anatosuchus are both comahuesuchids,[3] but work by Martinelli and Andrade et al. (2006) has suggested that A. minor is not a comahuesuchid.

[4] Comahuesuchus seems instead to be more closely related to Mariliasuchus.
