Priconodon (meaning "saw cone tooth") is an extinct genus of ankylosaurian dinosaur (perhaps nodosaurid), mainly known from its large teeth. Its remains have been found in the Early Cretaceous (Aptian-Albian age) Arundel Formation of Muirkirk, Prince George's County, Maryland, USA, and possibly the Potomac Group, also located in Maryland. As an ankylosaur, Priconodon would have been a large armored quadrupedal herbivore, though no size estimation has been done due to the scarcity of described remains.

==History of discovery== O. C. Marsh named the genus for USNM 2135, a large worn tooth from what was then called the Potomac Formation. As ankylosaurians were by and large unknown at the time, he compared it to Diracodon (=Stegosaurus) teeth. It was not identified as an ankylosaurian until Walter Coombs assigned it to Nodosauridae in 1978.
