We present measurements of the W boson mass at the Tevatron based on $$W \to \mu \nu$$ events collected by CDF and $$W \to e \nu$$ events observed by D0 in Run Ib (1994--95). The W boson mass measured in the preliminary CDF analysis is 80.43 $$\pm$$ 0.10 (stat) $$\pm$$ 0.12 (syst) $GeV/c^2$$. The D0 measured value is 80.44 \pm 0.10 (stat) \pm 0.07 (syst) $$GeV/c^2$$. We also describe measurements of the trilinear gauge boson couplings. The limits obtained on the WW\gamma and WWZ anomalous couplings from a combined D0 analysis using $$W\gamma$, $$WW \to \ell \nu \ell^\prime \nu^\prime$$, and $$WW/WZ \to e \nu jj$$ production are: -0.30 < $$\Delta\kappa$$ < 0.43, -0.20 < $$\lambda$$ < 0.20, and -0.52 < $$\Delta g^Z_1$$ < 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.
