Abstract We define rectangular central versions of the Campanato and Morrey spaces in \mathbb{R}^2 and consider the commutator operator of the rectangular 2-dimensional Hardy operator and a locally integrable function b acting on these Morrey spaces. We prove continuity of this operator when b belongs to a rectangular central Campanato space.

Keywords Rectangular Morrey-Campanato spaces, commutators, Hardy operator
