The Euparkeriidae are a family of small basal archosauromorph carnivores which lived from the Early Triassic to the Middle Triassic (Anisian). Their fossil remains are known so far from South Africa and Russia. Quite opposite to their sister family the Erythrosuchidae, the Euparkeriids were small, slender animals which were probably facultative bipeds.

The clade is named after "Euparkeria", a relatively well-known member of the group. Other possible Euparkeriids include "Dorosuchus", "Halazaisuchus", "Osmolskina", "Wangisuchus", and "Xilousuchus". The family name was first proposed by Friedrich von Huene in 1920; Huene classified the Euparkeriids as members of the Pseudosuchia. More recent analysis places the Euparkeriidae within Archosauriformes. The Euparkeriids lie close to the ancestry of the crocodiles, pseudosuchians, ornithodires and dinosaurs, but are not considered directly ancestral.
