Probes of Dark Sector from the ATLAS and CMS Experiments

We present a review of the most recent results in the search for Dark Matter in hypothesized Dark Sectors from the ATLAS and CMS experiments with data collected during the LHC second period of data taking at the center-of-mass energy of 13 TeV. Both conventional Dark Sector probes, such as mono object searches, Higgs invisible decays, supersymmetry Dark Matter, as well as new probes, such as Long-lived particles, dark QCD, heavy flavor coupled Dark Matter, are highlighted in this proceeding.
