In this paper, we consider a new subclass of analytic and bi-univalent functions associated with \(q\)-Ruscheweyh differential operator in the open unit disk \(\mathbb{U}\). For functions belonging to the class \(\Sigma_q(\lambda,\phi)\), we obtain estimates on the first two Taylor-Maclaurin coefficients. Further, we derive another subclass of analytic and bi-univalent functions as a special consequences of the results.
