Electroweak measurements performed by CDF and D0 are reported, corresponding to data collected at the centre-of-mass energy of 1.96 TeV with approximately a luminosity of $200pb^-1$. We present measurements of W and Z cross sections and decay asymmetries, recent results in diboson physics with new limits on anomalous couplings, preliminary results on the direct determination of the W width, and preliminary studies for the W mass measurement.
