The study of heavy flavour observables allows precision tests of the strong and electroweak sectors of the standard model. The search for rare processes provides highly sensitive probes of new physics, and access to multi-TeV scales through loop contributions. The LHC is a heavy flavour factory. Based on the exploration of the datasets acquired during Run I, the LHC collaborations have delivered a very significant set of measurements, in unique and complementary phase space and collision media. Several of these measurements are contributing to the clarification of existing puzzles, or resulted in the observation of new effects, new hadrons, and rare decays. In this seminar an overview of the Run I results will be provided. Sensitivity prospects for future LHC runs will be also mentioned.
