Amphilestidae is a family of Mesozoic mammals, generally regarded as eutriconodonts. They may form a paraphyletic or polyphyletic assemblage, though they share with gobiconodontids their similar tooth occlusion patterns and may be especially closely related to them.^[1] They occur from the Middle Jurassic to Cenomanian,^[2] and have a distribution across Laurasia.

The putative amphilestid Tendagurodon is considered a non-amphilestid member of Amphilestheria along with the newly described Condorodon by Gaetano and Rougier (2012).^[3]
