Discrete symmetries play a crucial role in particle physics. They appear abundantly in string model constructions. We focus here on the case of discrete R-symmetries which are intrinsically connected to the Lorentz group in extra dimensions and the appearance of N-extended supersymmetry. In that sense, discrete R-symmetries can be understood as "fractionally" extended supersymmetry. These symmetries reveal insight about the location of fields in extra dimensions (in particular the Higgs boson). Applications can be found in the solution of the μ-problem, suppression of proton decay and the structure of the soft terms of broken supersymmetry.
