The ALICE Collaboration has measured the inclusive production of muons from heavy flavour decays at forward rapidity, 2.5 $< y <$ 4, in pp and Pb-Pb collisions at $\sqrt {s_{NN}}$ = 2.76 TeV. The $p_{\rm T}$-differential inclusive cross section of muons from heavy flavour decays in pp collisions is compared to perturbative QCD calculations. The nuclear modification factor is studied as a function of pt and collision centrality. A weak suppression is measured in peripheral collisions. In the most central collisions, a suppression of a factor of about 3-4 is observed in 6 $< p_{\rm T} <$ 10 GeV/$c$. The suppression shows no significant $p_{\rm T}$ dependence.
