ALICE (A Large Ion Collider Experiment) aims at studying the behaviour of nuclear matter at high energy densities and the transition to the Quark Gluon Plasma (QGP), expected to occur in ultra-relativistic heavy ion collisions. Quarkonia production measurements in both Pb-Pb and pp collisions play a crucial role in the ALICE physics program. Quarkonium detection is possible in ALICE at both forward (in the dimuon channel) and mid-rapidity (in the dielectron channel). In 2010, the Large Hadron Collider has provided pp collisions at sqrt(s)=7 TeV and Pb-Pb collisions at sqrt(sNN)=2.76 TeV. The ALICE results on J/psi production in pp collisions are presented, along with the status of the Pb-Pb analysis.
