In this paper, we define the concept of \(n\)-ary \(\Gamma \)-semigroups as a generalization of \(n\)-ary semigroups and a generalization of \(\Gamma \)-semigroups. We prove some results and present many examples of \(n\)-ary \(\Gamma \)-semigroups. Also, we introduce the concept of Green’s equivalence relations on \(n\)-ary \(\Gamma \)-semigroups and prove some properties. Then, the notion of operator \(n\)-ary semigroup of an \(n\)-ary \(\Gamma \)-semigroup is defined. Finally, we define the notion of \(n\)-ary \(\Gamma \)-group.
