Unasuchus is an extinct genus of Early Cretaceous eusuchian belonging to the family Hylaeochampsidae.

The genus is named after Uña, a municipality in central Spain where fossils have been found.

[1] Unasuchus is known only from skull and jaw fragments, meaning that it initially defied precise classification within Crocodyliformes, but the cladistic analysis of Turcosuchus recovers Unasuchus as a derived hylaeochampsid.

[2][3] These remains have been found from the Barremian Las Hoyas Formation.
