Watongia is an extinct genus of non-mammalian synapsid from Middle Permian of Oklahoma. Only one species has been described, Watongia meieri, from the Chickasha Formation. It was assigned to family Gorgonopsidae by Olson and to Eotitanosuchia by Carroll. Reisz and collaborators assigned the genus in Varanopidae. Based on scaling with other synapsids, length of Watongia was about 2-2.5 meters, making it the largest of the family Varanopidae.
