The Palaeomerycidae is an extinct family of Neogene ruminants belonging to the infraorder Pecora. Palaeomerycids lived in Europe and Asia exclusively during the Miocene, coevolving with cervids, bovids, moschids, and tragulids there as part of a dramatic radiation of ruminants by the early Miocene.

The type species, Xenokeryx amidalae, was recovered from central Spain and bears a unique T-shaped protrusion from the top of the head. The specific epithet amidalae is in reference to the character Padmé Amidala from the Star Wars films "due to the striking resemblance that the occipital appendage of Xenokeryx bears to one of the hairstyles that the aforementioned character shows in The Phantom Menace feature film."
