The title mol­ecule, C18H19N3O3, lies on a mirror plane that bis­ects the adamantyl group. In the crystal, C—H⋯O and C—H⋯N inter­actions lead to supra­molecular chains along [100]. These assemble into layers in the ab plane via π–π inter­actions [centroid–centroid distance = 3.6548 (7) Å] between the oxadiazole and benzene rings.
