In this paper, we introduce a new subclass of analytic bi-univalent functions defined by using q-derivative operator. Further, we obtain both some initial and general coefficient bounds, and also Fekete-Szego inequalities for bi-univalent functions that belong to this class. Our results extend and improve some known results as special cases.
