In this article, we study factorial modules. Let M be a torsion free module over an integral domain R. We prove Gauss Lemma for modules and also we give Eisenstein irreducibility criterion for factorial modules. Furthermore, we give some applications of Eisenstein irreducibility criterion in R[X]-module M[X].
