The classifications of locally strongly convex isotropic equiaffine spheres and isotropic centroaffine hypersurfaces have been completed in the last decade, see [1] and [4]. In this paper, we consider isotropic Calabi hypersurfaces (also called graph immersion with Calabi normalization) and obtain a complete classification in the affine space R n+ 1. As a corollary, we give a new characterization of elliptic paraboloid: Elliptic paraboloids are the only constant isotropic Calabi hypersurfaces in R n+ 1.
