The CDF and D0 experiments at the Tevatron have used p anti-p
collisions at s**(1/2) = 1.96 TeV to perform electroweak physics measurements.
A program of precision electroweak tests of SM already started.
Measurements performed are: W and Z bosons production cross section using
different leptonic final states, dielectron Forward-Backward Asymmetry A_FB
and di-boson cross section production. We also report the prospects for the
W mass measurements.
