Stark broadening parameters, full widths at half intensity maximum and shifts for 18 spectral lines of Fe XXV, broadened by collisions with electrons, protons and Fe XXVII ions, have been calculated using the impact semiclassical perturbation formalism, for a grid of electron densities and temperatures of interest for neutron star atmospheres and their environment.
