"Aviatyrannis" is a genus of tyrannosaurid dinosaur from the Kimmeridgian stage of the Late Jurassic found in Portugal. It was described by Oliver Rauhut in 2003. The name means "Jurassic grandmother tyrant". It is one of the oldest tyrannosaurs ever found, the oldest being "Guanlong" (or "Iliosuchus" if it is indeed tyrannosauroid).

"Aviatyrannis" was perhaps a contemporary of another ancient tyrannosaur, the American "Stokesosaurus". "Aviatyrannis" was even originally assigned to "Stokesosaurus", and its fragmentary remains maintain the question of their synonymity open.

Like other early tyrannosaurs, "Aviatyrannis" was rather small. The holotype (IPFUB Gui Th 1), for example, is an ilium only 90 millimeters long. The type species, "Aviatyrannis jurassica", was described by Rauhut in 2003.
