We construct and analyse a mortar finite volume method for the discretization for selfadjoint elliptic boundary value problems in R 2 . This method is based on the mortar Crouzeix-Raviart non-conforming finite element spaces. We prove the optimal order H 1 -norm and L 2 -norm error estimates between
