Measurements of cross sections and couplings of the Higgs boson using the ATLAS detector at CERN’s LHC are presented. Data from proton proton collisions at [Formula: see text], 8 and 13 TeV are discussed. A range of production and decay couplings can be tested with a precision that depends on the generality of the assumptions made. Data at 7 and 8 TeV are also combined with CMS results to enhance the precision. The results are all consistent with predictions of the Standard Model.
