We present the latest results on electroweak physics obtained from the analysis of ppbar collisions at sqrt s = 1.8 TeV. The large data samples collected with the CDF and D0 detectors at the Tevatron Collider allow measurements of the top quark mass to a 3% accuracy and of the W boson to a 0.1% accuracy. Many precision measurements that test the Standard Model and probe its possible extensions are also described.
