Maximum rotation frequency of uniformly rotating neutron star models, determined by the mass shedding condition, {OMEGA}_max, has been calculated using a high precision numerical method, for a large set of equations of state of dense matter. The values of {OMEGA}_max for the subset of equations of state, which are causal within neutron star models, are fitted, within a few percent, by an empirical formula {OMEGA}_max≃0.77x10⁴s^–1(M_s/M_☉)^1/2(R_s/10km)^–3/2, where M_s, R_s are mass and radius of the maximum allowable mass configuration of non-rotating models. Systematic deviations from empirical formula are correlated with stiffness of the equation of state of dense matter.
