We prove that every variety with log-terminal singularities admits a crepantresolution by a smooth Artin stack. We additionally prove new McKaycorrespondences for resolutions by Artin stacks, expressing stringy invariantsof $\mathbb{Q}$-Gorenstein varieties in terms of motivic integrals on arcspaces of smooth stacks. In the crepant case, these McKay correspondences areparticularly simple, demonstrating one example of the utility of crepantresolutions by Artin stacks.
