An overview of the multi-messenger capabilities of the Pierre AugerObservatory is presented. The techniques and performance of searching forUltra-High Energy neutrinos, photons and neutrons are described. Some of themost relevant results are reviewed, such as stringent upper bounds that wereplaced to a flux of diffuse cosmogenic neutrinos and photons, bounds placed onneutrinos emitted from compact binary mergers that were detected by LIGO andVirgo during their first and second observing runs, as well as searches forhigh energy photons and neutrons from the Galactic center that constrain theproperties of the putative Galactic PeVatron, observed by the H.E.S.S.collaboration. The observation of directional correlations between ultra-highenergy cosmic rays and either high energy astrophysical neutrinos or specificsource populations, weighted by their electromagnetic radiation, are alsodiscussed. They constitute additional multi-messenger approaches aimed atidentifying the sources of high energy cosmic rays.
