Presented are the direct measurements of the W boson mass from the CDF and D0 experiments at the Fermilab p{bar p} collider using data from the 1994--1995 run. The W from the D0 experiment is 80.44 {+-} 0.12 GeV and the preliminary mass from CDF is 80.43 {+-} 0.16 GeV. Combining these mass values with the previous Tevatron measurements leads to a M{sub W} 80.41 {+-} 0.09 GeV. Also, presented is the new measurement of sin{sup 2} {Theta}{sub W}{sup on-shell} = 0.2199 {+-} 0.0020(stat) {+-} 0.0009(syst) from the deep inelastic neutrino scattering experiment (NuTeV) at Fermilab. In the context of the Standard Model this can be interpreted as a M{sub W} = 80.53 {+-} 0.11 GeV.
