Protosuchidae is a family of basal crocodyliform reptiles that lived from the Late Triassic to the Late Cretaceous.

This family should not be confused with Protosuchia, which is an informal evolutionary grade of primitive crocodiliforms Triassic protosuchids are known from Lesotho, Argentina, and Arizona.

Jurassic protosuchids are known from Nova Scotia, Poland, South Africa, and Arizona.

Below is a phylogeny of protosuchids modified from Bronzati et al.
