Using 609583 $K_{S}^{0}\to\pi^{+}\pi^{-}$ decays from the $e^{+}e^{-}\to K_{S}^{0}K_{L}^{0}$
reaction around the $\phi(1020)$ resonance with the CMD-3 detector,
the neutral kaon mass has been measured.
Using the beam energies control by the back-scattering laser light photons, and a normalization to the
world average $\phi$-meson mass, the neutral kaon mass is determind to be
m($K^0$) = 497.587 $\pm$ 0.004(stat.) $\pm$ 0.012(syst.) \mevcc.
