Actiocyon was an extinct genus of ailurid that existed from the Middle Miocene of North America. The type species, Actiocyon leardi, was described in 1947 by the American paleontologist Chester Stock.
Description
The holotype consisted of portions of a snout containing the palate with some teeth. Stock noted overall similarities to their contemporary genus Alopecocyon of Europe, though he tentatively classified Actiocyon as a procyonid due to the structure of fourth premolar and first molar.{{cite journal|author-first=C. |author-last=Stock |year=1947 |title=A peculiar new carnivore from the Cuyama Miocene, California. |journal=Bulletin of the Southern California Academy of Sciences |volume=46 |issue= |pages=84–89 | issn = 0038-3872 |url=https://authors.library.caltech.edu/113142/1/Stock_1947p84.pdf}} Some later authors have suggested Actiocyon to be a junior synonym of Alopecocyon,{{cite journal | last1 = Peigné | first1 = S. | last2 = Salesa | first2 = M.

(2016) and was the earliest known simocyonine from North America.
