Heavy quarkonium states are expected to provide essential information on the properties of the high-density strongly-interacting system formed in the early stages of high-energy heavy-ion collisions. Such probes are especially promising at LHC energies, where heavy quarks are copiously produced. ALICE is the experiment at the LHC mainly dedicated to the study of nucleus-nucleus collisions. At forward rapidity (2.5 < y < 4), the production of heavy quarkonium states is measured down to pT = 0 via their mu+mu- decay channels in the Forward Muon Spectrometer. After a short description of the apparatus, the analysis of the inclusive J/psi production in the first Pb-Pb data collected in the fall 2010 at a center of mass energy of sqrt(s_NN) = 2.76 TeV will be presented. Preliminary results on the nuclear modification factor (R_AA) and the central to peripheral nuclear modification factor (R_CP) will then be discussed.
