Standard Model physics at ATLAS

The latest advances in Standard Model measurements performed by the ATLAS experiment at the LHC are discussed. Vector-boson scattering processes have been observed in several final states ($ZZ$, $WZ$, same-sign $WW$), and evidence has been reached in the $Z\gamma$ final state. The experimental precision of QCD measurements has reached the same order as the theoretical uncertainties on the NNLO calculations. Evidence for the triboson $WVV$ final state has been achieved. The latest results on $V$+jets, $Z\gamma$, $W^{+}W^{-}$ and direct photons production are presented. New results on jet substructure and forward proton tagging program are also discussed.
