Observational data on dark matter (DM) together with requirements from Big Bang nucleosynthesis imply the existence of some source of non-baryonic DM. Since the electroweak standard model (SM) does not possess any such non-baryonic DM candidate, this problem consitutes one of the few evidences we have for new physics beyond the SM. After discussing extensions of the SM with massive neutrinos in the eV range, I will focus on supersymmetric (SUSY) generalizations of the SM. I will show that the nature and amount of DM in these models is closely linked to the fundamental question of the breaking of SUSY. The interplay between particle physics and cosmology in this context will be emphasized.
