In this paper, we study the Ext-algebras of graded skew extensions. For a connected graded algebraAand a graded automorphismofA, we analyze the Yoneda product of the Ext-algebra of graded skew extension, and prove this Ext-algebra is anR-smash product of the Ext-algebra ofAand the one of polynomial algebrak[z].
