It is here presented the diboson production cross section measured by the CMS collaboration in \(pp\) collisions data at \(\sqrt{s}\)=7 TeV. \(W \gamma\) and \(Z \gamma\) results from 2010 analyses (36 pb\(^{-1}\)) are presented together with 2011 first measurements of \(WW\), \(WZ\) and \(ZZ\) final states obtained using 1.1 fb\(^{-1}\). Results obtained with 2010 data are also interpreted in term of anomalous triple gauge couplings.
