In the present paper, the notion of generalized (s, m, ϕ)-preinvex function is applied to establish some new generalizations of Ostrowski type inequalities via fractional integral operators. These results not only extend the results appeared in the literature (see [1]) but also provide new estimates on these type. Some applications to special means are also given.
