Pasawioops is an extinct genus of dissorophoid euskelian temnospondyl within the family Amphibamidae. It has been found from the fissure fills of Richards Spur in Comanche County, Oklahoma, which are Early Permian in age. It is known from two skulls. The holotype skull, called OMNH 73019, is complete and well preserved. The second skull, OMNH 73509, only has the posterior portion preserved but is almost twice the size of OMNH 73019. Pasawioops has a characteristically long skull with enlarged tabular and postparietal bones. The teeth of Pasawioops are monocuspid and recurved. Unlike other amphibamids such as Gerobatrachus, the teeth are not pedicellate, or narrow at the base.
Pasawioops is closely related to Micropholis, an amphibamid known from the Late Triassic Beaufort Group in the Karoo Basin of South Africa. The two genera are sister taxa, and form a clade along with Tersomius that is distinct from other amphibamids such as Amphibamus, Doleserpeton, and Eoscopus.
