Orienspterodon ("eastern Pterodon") is an extinct genus of hyaenodonts from extinct paraphyletic subfamily Hyainailourinae within paraphyletic family Hyainailouridae, that lived from middle to late Eocene in China and Myanmar.^[5] Type species O. dahkoensis was originally assigned to genus Pterodon in 1975, but was eventually assigned to its own genus in 2007.^[1]
