Argentoconodon (meaning "Argentina cone tooth") is an extinct genus of theriimorph mammal from the Cañadón Asfalto Formation of the Cañadón Asfalto Basin in 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.{{cite journal |last1=Rougier |first1=Guillermo W. |last2=Garrido |first2=Alberto |last3=Gaetano |first3=Leandro |last4=Puerta |first4=Pablo |last5=Corbitt |first5=Cynthia |last6=Novacek |first6=Michael J. |title=First Jurassic triconodont from South America |journal=American Museum Novitates |issue=3580 |date=2007 |pages=1–17 |doi=10.1206/0003-0082(2007)3580[1:FJTFSA]2.0.CO;2 |hdl=2246/5873 |s2cid=85676529 |url=https://zenodo.org/record/5388278 |hdl-access=free }} New material described in 2011 show that Argentoconodon was similar to Ichthyoconodon, Jugulator and Volaticotherium within the family Triconodontidae,{{cite journal |last1=Gaetano |first1=Leandro C. |last2=Rougier |first2=Guillermo W. |title=New materials of Argentoconodon fariasorum (Mammaliaformes, Triconodontidae) from the Jurassic of Argentina and its bearing on triconodont phylogeny |journal=Journal of Vertebrate Paleontology |date=July 2011 |volume=31 |issue=4 |pages=829–843 |doi=10.1080/02724634.2011.589877 |bibcode=2011JVPal..31..829G |s2cid=85069761 |hdl=11336/68497 |hdl-access=free }} and possibly also Triconolestes.{{cite journal |last1=Averianov |first1=A.
