Preliminary electroweak results are discussed from the Fermilab experiments, CDF and DO, based on Tevatron run 1b data. These include an updated precision measurement of the W mass which when combined with previous Tevatron, CERN S[bar p]S, and LEP-II results gives a combined world average M[sub W]= 80.40[+-] 0.08 GeV/c[sup 2]. Also presented are new limits on anomalous gauge boson self-couplings, measurement of the W charge asymmetry, [sigma][center-dot]B(W[yields][tau][nu][sub[tau]]), and limits on quark/lepton compositeness from high mass Drell-Yan production.
