Hints of physics beyond the Standard Model in the flavour sector

Flavour physics represents one of the most interesting and, at the same time, less understood sector of the Standard Model. After a brief introduction to this filed, I will focus the attention to a series of recent results in B physics which seem to indicate a coherent pattern of deviations from the Standard Model predictions. I review these hints, addressing theoretical uncertainties and possible New Physics interpretations. Possible connections with direct searches of physics beyond the Standard Model at the high-energy frontier will also briefly addressed.
