Let R be a commutative ring with identity and M be an R-module. A proper ideal I of R is said to be a z^-ideal if for each a I the intersection of all minimal prime ideals containing a is contained in I. The purpose of this paper is to introduce the notion of z^-submodules of M as an extension of z^-ideals of R. Moreover, we investigate some properties of this class of submodules when M is a reduced multiplication R-module.
