Sumario:The precise measurement of known Standard Model processes is an important part of the ATLAS physics programme. A wide spectrum of final states is covered ranging from the measurement of the total proton-proton cross section down to very rare processes like the production of same-sign W pairs. These measurements serve to constrain phenomenological models of the strong interaction, provide precision tests of perturbative QCD calculations up to the next-to-next-to-leading order, improve our knowledge on the proton structure, measure fundamental Standard Model parameters to high precision or test the Electroweak gauge structure, providing model-independent constraints on new physics. Recent highlights of Run-1 measurements are reported, including new results on multi-differential jet and photon production, precision measurements with single W and Z bosons and multiboson production. The ATLAS Standard model group is also committed to perform several measurements with the data collected in the early Run 2 of the LHC with pp collisions at 13 TeV. Several of those are expected to be available at the time of the conference, including measurements of the properties of minimum bias interactions, the total inelastic cross section and well as early cross section measurements involving W and Z bosons, jets and isolated photons.
