Studies of vector boson production at CMS

The most recent diboson production and electroweak physics results from CMS are presented. This overview is focused on the precise measurement of WW, WZ, ZZ and $\gamma\gamma$ production, as well as W or Z production in association with a photon. These results are interpreted in terms of constraints on anomalous triple gauge couplings, while the study of WW$\gamma$ and WZ$\gamma$ production is used to set limits on anomalous quartic gauge couplings. Selection of the latest electroweak results is also presented.
