Xiphodontidae (from Ancient Greek ξίφος (xíphos), meaning "sword", and ὀδούς (odoús), meaning "tooth") is an extinct family of herbivorous even-toed ungulates (order Artiodactyla), endemic to Europe during the Eocene 40.4—33.9 million years ago, existing for about 7.5 million years. Paraxiphodon suggests that they survived into the Lower Oligocene, at least.
