Abstract: 

The re-normalization process in quantum field theory on commutative space-time was expressed in terms of a Hopf algebra structure, the Connes-Kreimer algebra. Recently, some models of field theories on the non-commutative Moyal space were proven to be re-normalizable also. Despite the non-local nature of these models, we construct here the Hopf algebra structure adapted for the process of re-normalization of these non-commutative field theory.
