Sumario:The ATLAS collaboration has performed studies of a wide range of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-QCD measurements include studies of underlying event, vector meson production and quark confinement effects. Differential measurements of inclusive and multi-jet production provide stringent tests of high-order QCD predictions and provide input for determination of parton density functions. Measurements of isolated inclusive and di-photons cross sections for high p_T photons test various theoretical predictions and constrain parton density functions. In addition the total pp cross section at 7 TeV, together with the elastic and inelastic contributions, is measured and compared to various models. An overview of these results is given. Prospects at HL-LHC will also be discussed as an outlook.
