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.
