Dark Matter searches with the ATLAS detector

This talk presented recent results for searches of Dark Matter signals with the ATLAS detector at the LHC. It covers signatures where potential DM particles are produced in association with Standard Model ones such as jet, photon, top-quark pairs, vector bosons as well as Higgs boson. In addition, direct searches for DM-SM mediator are shown in the high mass region of dijets final states. Finally, limits within simplified models framework and comparison with direct detection experiments are also presented.
