We present electroweak physics results from the DZero experiment using data from collisions at √(s) = 1.8 TeV, concentrating on single W and Z production cross sections and the production of electroweak gauge boson pairs. The inclusive cross sections times branching ratios for W and Z production have been measured and are used to determine the inclusive width of the W boson. Direct tests of the WWγand WWZ trilinear gauge boson couplings are derived from the study of diboson production. These measurements test the non-abelian self couplings of the W, Z and photon, one of the most direct consequences of the SU(2)L × U(1)Y gauge symmetry. We present measurements of the WWγcoupling based on p pbar --> l νγ+ X and limits on anomalous WWZ and WWγcouplings based on searches for p \pbar --> W+ W- + X --> l l' ν\nubar + X and p \pbar --> WW / WZ + X --> e ν+ jets + X. We also present limits on the ZZγand Zγγcouplings based on p pbar --> l+ l- γ+ X events.
