A measurement of the ZZ production cross section in proton-proton collisionsat sqrt{s} = 7 TeV using data collected by the ATLAS experiment at the LHC ispresented. In a data sample corresponding to an integrated luminosity of1.02fb-1, 12 events containing two Z boson candidates decaying to electronsand/or muons were observed. The expected background contribution is0.3^{+0.9}_{-0.3} (stat) ^{+0.4}_{-0.3} (syst) events. The total cross sectionfor on-shell ZZ production has been determined to be \sigma_{ZZ}_{tot}=8.4^{+2.7}_{-2.3}(stat) ^{+0.4}_{-0.7}(syst)\pm 0.3 (lumi) pb$ and iscompatible with the Standard Model expectation of 6.5^{+0.3}_{-0.2} pbcalculated at the next-to-leading order in QCD. Limits on anomalous neutraltriple gauge boson couplings are derived.
