Amphibolips quercusostensackenii is a species of gall wasp in the family Cynipidae.

This species induces globular galls on the leaves of members of the red oak group (Quercus sect.

These galls are roughly 7 to 9 mm in diameter,[2] and contain a central filament-supported cell[3] where pupation occurs.

Adults are described to have emerged from the galls between 8 and 15 July in the Chicago area.

However, a 2002 review reclassified it to the closely related genus Amphibolips based on the morphology of the adult wasp.
