Acidomomys is a plesiadapiform mammal of the family Paromomyidae, a precursor to the primates or very closely related to them.

Acidomomys hebeticus fossils were described from the late Paleocene, Clarkforkian freshwater limestones of Clarks Fork Basin, Wyoming.[1] They appear to have an unusual dental eruption sequence, differing from Plesiadapis and other primitive primates and possibly indicating differences in facial appearance or life history.[citation needed]
