Recent measurements of diboson production in proton-proton collisions at the LHC, performed by the CMS Collaboration, are summarized. Studies of ZZ production, WZ and WW production at $\sqrt{s} = 13$~TeV, $\mathrm{WV} \to \ell\nu\mathrm{q}\bar{\mathrm{q}}$ ($\mathrm{V} = \mathrm{W}^\pm$ or Z, $\ell = \mathrm{e}$ or $\mu$) at $\sqrt{s} = 13$~TeV, and $\mathrm{Z}\gamma \gamma$ and $\mathrm{W}\gamma \gamma$ at $\sqrt{s} = 8$~TeV are reported. Inclusive and differential cross section measurements and limits on anomalous triple gauge couplings are reported, as well as a measurement of the $\mathrm{Z} \to 4\ell$ branching fraction.
