The heavy-ion physics program at the LHC aims at characterizing a high energy density and high temperature nuclear matter state, called Quark-Gluon Plasma (QGP). Due to its extreme conditions, the plasma is composed of quasi-free quarks and gluons that can interact, while not being confined into hadrons. Hard probes are very useful tools to study the QGP properties since they are abundantly produced at the LHC energy regime, via hard scattering processes, and they can experience the full evolution of the system, while passing through it. Heavy-flavour measurements can be very helpful to investigate the energy loss mechanisms that occur between different partons in the plasma. The higher mass of such quarks can be used to study possible differences in the interactions between heavy and light quarks with the medium constituents. The LHC also established an important program of p-Pb collisions in order to study cold nuclear matter effects, caused by the implication of heavy nuclei as input of the collisions and not by the formation of the deconfined plasma. The measurements of those effects are important in the heavy-flavour sectors, in order to better understand the results obtained in Pb-Pb collisions and to study shadowing and saturation effects that can cause modifications of their productions.

A review of the ALICE heavy-flavour measurements will be presented. Focus will be given on the results obtained with Run1 data in Pb-Pb and p-Pb collisions at √s_NN = 2.76 TeV and √s_NN = 5.02 TeV respectively.
