        Abstract: The Quasilocalized Charge Approximation has been devised
        for the analysis of dynamical processes in strongly coupled
        Coulomb and Yukawa systems. Its physical foundation is that in
        strongly coupled systems particles are trapped in the local minima
        of the fluctuating potential for a time period long compared with
        the characteristic time of collective oscillations. Thus the
        particles occupy randomly located, but at the same time strongly
        correlated sites and undergo oscillations around them. At the same
        time the equilibrium configuration undergoes a slow rearrangement.
        We review the formal development and recent extensions of the
        theory leading to the formulation of the dielectric response
        function as a functional of the equilibrium pair correlation
        function. Molecular Dynamics result are shown to corroborate and
        quantify the details of the underlying physical model. Theoretical
        results based on the model for a number of physical systems ~VOCP,
        complex plasmas, semiconductor bilayers, 2D electron gas- are
        compared with Molecular Dynamics simulation and experimental data.
