Argentoconodon (meaning "Argentina cone tooth") is an extinct genus of theriimorph mammal from the Cañadon Asfalto Formation of Patagonia. When originally described, it was known only from a single molariform tooth, which possessed a combination of primitive and derived features. The tooth is currently held in the Museo Paleontológico Egidio Feruglio, where it was given the specimen number MPEF-PV 1877. New material described in 2011, including most of a skull and many mostly complete skeletons, show that Argentoconodon was similar to Ichthyoconodon, Jugulator and Volaticotherium within the family Triconodontidae, and possibly also Triconolestes.
