  Heavy Quarks will be abundantly produced in Heavy Ion Collisions at LHC
energies. Both, the production of open heavy flavoured mesons and quarkonia
will probe the strongly interacting medium created in these reactions. In
particular, the ALICE detector will be able to measure heavy flavour production
down to low transverse momentum, combining leptonic and hadronic channels,
covering a large rapidity range $|\eta|<0.9$ and $-4<\eta<-2.5$. In this talk
we will present the main physics motivations for the study of heavy flavour
production at LHC energies and some examples of physics analyses developed by
the heavy flavour working group of ALICE.
