  We investigate the possibility that both dark matter and the long-standing
discrepancy in the anomalous magnetic moment of the muon may be explained
within the MSSM. In light of the stringent bounds from direct detection, we
argue that the most promising viable scenarios have bino-like dark matter
produced via either bino-wino or bino-slepton co-annihilation. We find that the
combination of next-generation direct detection experiments and the LHC will be
able to probe much of the interesting parameter space, however a future
high-energy collider is needed to comprehensively explore this scenario.
