Abstract ALICE is the dedicated heavy-ion experiment at the LHC. Due to the unique particle identification capabilities of the central barrel detectors ( | η | 0.9 ), J / ψ can be measured in the di-electron channel in the very demanding environment of central Pb–Pb collisions at the LHC. In addition J / ψ are measured at forward rapidity ( 2.5 y 4 ) with a dedicated muon spectrometer. ALICE is the only LHC experiment with an acceptance for J / ψ that reaches down to p T = 0 at both, mid- and forward rapidity. Preliminary results on the nuclear modification factor of the inclusive J / ψ production at mid- and forward rapidity in Pb–Pb collisions at s N N = 2.76 TeV are presented.
