Allodontidae (from ancient Greek "ἄλλος" "ὀδούς", "different tooth") is a family of extinct multituberculate mammal that lived in what is now North America during the Upper Jurassic period. They were relatively early mammals and are within the informal suborder of "Plagiaulacida". The family was named by Othniel Charles Marsh in 1889. Two genera are recognized: "Ctenacodon" and "Psalodon".
