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.

In this report, we summarize the latest results of the top-quark mass and electroweak measurements from the Tevatron. Since the world combination of top-quark mass measurements was done, CDF and D0 experiments improved the precision of several results. Some of them reach the relative precition below 1% for a single measurement. From the electroweak results, we report on the WW and WZ production cross section, measurements of the weak mixing angle and indirect measurements of W boson mass. The Tevatron results of the weak mixing angle are still the most precise ones of hadron colliders.

The large amounts of data being integrated by the CDF and D0 experiments at the Fermilab Tevatron allow for large samples of vector bosons to be collected. As a result precise measurements of the properties of inclusive W and Z production can be made. At the same time studies of events with multiple vector bosons may be studied for insight into the structure of the Standard Model.

Recent Electroweak measurements by the CDF and D0 collaborations in p{bar p} collisions {radical}s = 1.96 TeV are presented here. Measurements of W, Z and diboson production cross sections as well as W asymmetry using integrated luminosities up to 800 pb{sup -1} are reviewed. Limits on triple gauge anomalous couplings on diboson production are discussed elsewhere.
