Abstract
Let G be an abelian group with identity

. Let R be a G-graded commutative ring with identity 1, and
M

be a graded R-module. In this paper, we introduce the concept of graded
J

r
{J}_{gr}
-classical 2-absorbing submodule as a generalization of a graded classical 2-absorbing submodule. We give some results concerning of these classes of graded submodules. A proper graded submodule
