Abstract In this overview presentation I report on selected Standard Model (SM) physics highlights obtained by the ATLAS and CMS experiments in the first three years of data taking (Run I) at the new Large Hadron Collider (LHC) at CERN. By far the most important and exciting result of LHC Run I has been the observation of a new boson with a mass of 125 GeV, consistent with the properties of the SM Higgs boson. The discovery of the Higgs boson has brought the last missing piece of the Standard Model but the talk has given also an overview of the main results on di‐boson production, heavy flavour physics (b‐quark rare decays and CP violation; top‐quark mass and properties) and QCD. Finally a brief discussion on LHC future program. LHC is just now restarting operation at higher energy. New data will certainly give more detailed informations on the Higgs boson and by the end of this decade LHC experiments will have collected ten times more proton‐proton (pp) collisions. The Standard Model processes have been holding up to scrutiny over several orders of magnitude in production cross section but we are just at the beginning of the TeV scale exploration.
