We report a precise measurement of the weak mixing angle from the ratio of neutral current to charged current inclusive cross sections in deep-inelastic neutrino-nucleon scattering. The data were gathered at the CCFR neutrino detector in the Fermilab quadrupole-triplet beam, with neutrino energies up to 600 GeV. Using the on-shell definition, sin²{{{θ}}}W$==1-${M}W²$/${M}Z²$, we obtain ${sin}²θW=0.2218±{}0.0025(stat)±{}0.0036(expt syst)±{}0.0037(model).
