In this present work, the authors obtain Fekete-Szeg inequality for certain normalized analytic function defined on the open unit disk for which lies in a region starlike with respect to 1 and is symmetric with respect to the real axis. Also certain applications of the main result for a class of functions defined by Hadamard product (or convolution) are given. As a special case of this result, Fekete-Szeg inequality for a class of functions defined through fractional derivatives are obtained.
