The existence of neutrino mass and mixing points towards physics beyond the standard model. An overview of the possibility of having neutrino masses in supersymmetric theories will be presented. In many of the cases, the models that give neutrino masses and mixing have independent motivations of their own, from the viewpoint of supersymmetry as well, and can be tested at the LHC. Since the search for supersymmetry is already an important goal at the LHC, it should be really interesting to look for the correlations between the signatures at the LHC and the observations in the neutrino sector. - The lecture is a pedagogical introduction into the field.
