We report the determination of $$\sin^{2} \theta_{W}$$ in ν - N deep inelastic scattering from the NuTeV experiment. Using separate neutrino and anti-neutrino beams, NuTeV is able to extract $$\sin^{2} \theta_{W}$$ with low systematic errors from the Paschos-Wolfenstein variable R^-, a ratio of differences of neutrino and anti-neutrino neutral-current and charged-current cross-sections. NuTeV measures $$\sin^{2} \theta_{W}$$^(on-shell) = 0.2253 ± 0.0019(stat) ± 0.0010(syst), which implies M_W = 80.26 ± 0.11 GeV.
