We present measurements of the W boson mass at the Tevatron based on W → μν events collected by CDF and W → e ν events observed by D0 in Run Ib (1994--95). The W boson mass measured in the preliminary CDF analysis is 80.43 ± 0.10 (stat) ± 0.12 (syst) GeV/c2. The D0 measured value is 80.44 ± 0.10 (stat) ± 0.07 (syst) GeV/c2. We also describe measurements of the trilinear gauge boson couplings. The limits obtained on the WWγand WWZ anomalous couplings from a combined D0 analysis using Wγ, WW → ℓ νℓ^′ ν^′, and WW/WZ → e νjj production are: -0.30 < Δκ< 0.43, -0.20 < λ< 0.20, and -0.52 < ΔgZ1 < 0.78, for a dipole form factor scale of 2 TeV. Improved limits have been obtained by combining these results with the limits derived from the LEP experiments.
