The search for New Physics has been one of the main goals of particle physics for several years. Despite the fact that the Standard Model does not seem a good candidate to be the final theory of elementary interactions it has been able to describe many sub-atomic phenomena with an impressive precision. A promising way to look for New Physics consists of the measurement of processes which are highly suppressed in the SM, where New Physics can in principle have relatively large effects. Rare decays of B-mesons are particularly interesting since several observables sensitive to New Physics and where QCD uncertainties are well under control can be built. I will discuss present measurements and prospects for the study of rare B-decays at LHCb. In particular, the measurement of the branching ratio of the Bs->mumu decay and angular asymmetries in the decay Bd->K*mumu will be discussed.
