Non‐singular toric embeddings with dual defect are classified. The associated polytopes, called defect polytopes, are proven to be the class of Delzant integral polytopes for which a combinatorial invariant vanishes. The structure of a defect polytope is described. 2000 Mathematics Subject Classification 14M25, 52B20, 05A18.
