CMS results on heavy flavour and quarkonia

The CMS collaboration has recorded 150 inverse microbarns and 35 inverse nanobarns of PbPb and pPb collisions, at 2.76 TeV and 5.02 TeV, respectively. This presentation reports the results of the heavy quark measurements including quarkonia and B mesons. A particular emphasis is given to the most recent results regarding the suppression of J/Psi, Psi(2S) and the upsilon states in Pb+Pb collisions, and the study of cold nuclear matter effects based on p+Pb collisions.
