We consider static black holes, which are bosonic solutions of supersymmetric theories. We will show that supersymmetry provides a natural framework for a discussion of various properties of such static black holes. The most fundamental property of simple global supersymmetry, non-negativeness of the energy, is generalized in the black hole theory to cosmic censorship. The SUSY classification of static black holes will be presented in terms of central charges of supersymmetry algebra. The mass, the temperature and the entropy of these black holes are simple functions of supersymmetry charges. The extreme black holes have zero temperature and some unbroken supersymmetries.
