This contribution presents recent ALICE measurements on charmonium production at forward rapidity in pp collisions at √ s = 7 TeV, p-Pb at √ sNN = 5.02 TeV and Pb-Pb at √ sNN = 2.76 TeV. The charmonium production cross sections in pp collisions are in good agreement with calculations within the NRQCD approach. The comparison between J/ψ and ψ(2S) yields in p-Pb collisions indicates the presence of Cold Nuclear Matter effects on charmomium production in the final state. In Pb-Pb collisions the
