'''Hyaenodontidae''' ("hyena teeth") is a family of placental mammals in the extinct superfamily Hyaenodontoidea. Hyaenodontids arose during the early Eocene and persisted well into the early Miocene. Fossils of this group have been found in Asia, North America and Europe.<ref name="TPBDB">{{Cite web |url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=40903 |title=The Paleobiology Database Hyaenodontidae page |access-date=2009-04-10 |archive-date=2012-10-12 |archive-url=https://web.archive.org/web/20121012165201/http://paleodb.org/cgi-bin/bridge.pl?action=checkTaxonInfo&taxon_no=40903&is_real_user=1 |url-status=live }}</ref><ref name="Lambert1988">{{aut|Lambert, David and the Diagram Group}} (1985): ''The Field Guide to Prehistoric Life.''
