The ARGO-YBJ experiment is an unconventional air-shower array designed for studying astronomical gamma-ray sources at energy greater than few hundred GeV and cosmic-ray physics at energy greater than about 1 TeV. The detector fulfils the requirements to achieve such goals thanks to its high-altitude location, 4300 meters a.s.l. on the Tibet plateau, and to its structure: a full-coverage layer of Resistive Plate Chambers (RPCs) covering a surface of 78 x 74 m^2, surrounded by a guard ring of RPCs enclosing a total surface of about 11000 m^2. ARGO-YBJ has been running with the complete layout since November 2007, collecting about 4 x 10^11 events. The main results obtained by ARGO-YBJ, namely the cosmic-ray anisotropy, the monitoring of gamma-ray sources and the limit on the antiproton-proton ratio in the primary cosmic radiation, will be discussed.
