Quarkonia constitute a sensitive probe of the hot and dense matter created in heavy-ion collisions at high energy. Bottomonium states are particularly interesting because they cannot be produced from the decay of long lived hadrons and their production from statistical hadronization or kinetic regeneration is expected to be marginal. They represent therefore a unique tool to probe the deconfined phase produced in heavy-ion collisions. We present Υ measurements obtained with the ALICE muon spectrometer in pp collisions at √ s = 7 TeV, in p–Pb collisions at √sNN = 5.02 TeV and in Pb–Pb collisions at √sNN = 2.76 TeV. Results are obtained in the rapidity range 2.5 < ylab < 4 and down to zero transverse momentum. They are compared to other LHC data and to model predictions.
