In this paper, we study (m,n)-regular ordered Γ-semigroups through ordered (m, n)-Γ-ideals. It is shown that if (S,Γ, ·,≤) is an ordered Γ-semigroup; m,n are non-negative integers and A(m,n) is the set of all ordered (m,n)-Γ-ideals of S. Then, S is (m,n)-regular⇐⇒ ∀A ∈ A(m,n), A = (A ΓSΓA]. It is also proved that if (S,Γ, ·,≤) is an ordered Γ-semigroup; m,n are nonnegative integers; R(m,0); L(0,n) is the set of all (m, 0)-Γ-ideals and (0, n)-Γ-ideals of S, respectively. Then, S is (m, n)-regular ordered Γ-semigroup ⇐⇒ ∀R ∈ R(m,0)∀L ∈ L(0,n), R ∩ L = (RΓL ∩ RΓL].
