The measurement of the ZZ production cross section performed by the ATLAS detector in LHC proton-proton collisions at √s = 7TeV is discussed. The results are based on an integrated luminosity of 4.6 fb−1 collected by ATLAS in 2011 with a fully operational detector and stable beam conditions. The normalized differential cross sections in bins of various kinematic variables together with limits on ZZZ and ZZγ anomalous triple gauge couplings derived using the transverse momentum of the leading Z boson are also presented
