The nature of the dark matter is one of the greatest mysteries of modern cosmology and particle physics. Besides the standard scenario of stable WIMPs several models of decaying dark matter have been discussed in the literature. In this talk I will discuss a theory with broken R-parity where the gravitino forms a candidate for unstable dark matter. After a review of the cosmological motivation for the scenario I will discuss its phenomenology, in particular elaborating on indirect searches using observations of cosmic rays. I will also mention some implications for the LHC.
