Hahnodon ("Hahn's tooth") is an extinct genus of mammaliaforms from the Early Cretaceous Ksar Metlili Formation in Morocco. Although originally considered to be a relatively early member of the extinct clade Multituberculata, recent studies indicate that it instead is a haramiyid.{{Cite web|url=https://www.natureasia.com/en/research/highlight/12522/|title=Fossils: Youngest known haramiyid fossil found in North America | Nature | Nature Portfolio|access-date=2018-05-26|archive-date=2022-05-17|archive-url=https://web.archive.org/web/20220517105652/http://www.natureasia.com/en/research/highlight/12522|url-status=dead}}

Classification
Denise Sigogneau-Russell (1991) classified Hahnodon as a member of Multituberculata, but others later considered it to be related to members of Haramiyida.Butler, P. M., & Hooker, J. J. (2005).

Clemens. 2006. A possible Late Cretaceous "haramiyidan" from India. Journal of Vertebrate Paleontology 26(2):488-490 The description of Cifelliodon from North America confirmed that Hahnodon — and by extension, Hahnodontidae — belong to Haramiyida.Adam K.
