In this work, we obtain the Schrödinger equation solutions for the Kratzer potential plus screened Coulomb potential model using the series expansion method. The energy eigenvalues is obtained in non-relativistic regime and the corresponding unnormalized eigen function. Three special cases were obtained. We applied the present results to calculate heavy-meson masses of charmonium and bottomonium , and we got the numerical values for1S, 2S, 1P,2P, 3S, 4S,1D,2D and 1F states. The results are in good agreement with experimental data and the work of other researchers.
