Caenagnathasia ('recent jaw from Asia') is a small caenagnathid oviraptorosaurian theropod from the Late Cretaceous of Uzbekistan.

The type species Caenagnathasia martinsoni was named and described in 1994 by Philip J. Currie, Stephen Godfrey and Lev Nesov.

The generic name is a combination of a reference to the species' placement in the Caenagnathidae, with Asia, the continent of its provenance.

The specimen was found near Dzharakuduk in layers of the Bissekty Formation, dating to the Turonian-Coniacian, around 90 mya, making it the oldest known caenagnathoid.

The jaw fragments are only a few centimetres long and total skull length has been estimated at 3 inches (7.6 cm).
