We review the application of non abelian discrete groups to the theory of neutrino masses and mixing, which is strongly suggested by the agreement of the TriBimaximal (TB) mixing pattern with experiment. After summarizing the motivation and the formalism, we discuss specific models, based on A4, S4 and other finite groups, and their phenomenological implications, including lepton flavor violating processes, leptogenesis and the extension to quarks. In alternative to TB mixing the application of discrete flavor symmetries to quark-lepton complementarity and Bimaximal Mixing (BM) is also considered.
