Sumario:Various electroweak measurements have already been performed at ATLAS and CMS since the start of the LHC. These allow for precision tests of the electroweak dynamics of the Standard Model, but also challenge next-to-next-to-leading-order predictions. Differences between measurements and Standard Model predictions could prove evidence for new phenomena. A review of the latest results in $W/Z$ and diboson physics is given. Those consist of the measurement of the high-mass Drell-Yan differential and double-differential cross section, the study of the transverse momentum of the $Z/\gamma^{*}$ using the $\phi^{*}_{\eta}$ variable and azimuthal correlations for events where a $Z$ boson is produced in association with jets. Various diboson measurements are presented and measurements are in general found to be well described by the Standard Model predictions. These measurements test the non-Abelian gauge structure and limits on anomalous triple gauge couplings are derived, which are of impact comparable to the corresponding LEP and Tevatron results.
