We demonstrate that the recent measurement of the anomalous magnetic moment of the muon and dark matter can be simultaneously explained within the Minimal Supersymmetric Standard Model. Dark matter is a mostly-bino state, with the relic abundance obtained via co-annihilations with either the sleptons or wino. The most interesting regions of parameter space will be tested by the next generation of dark matter direct detection experiments.

Current data restrict the g~-SUGRA scenario to tanβ ≳ 5 and M0 ≳ 20 tanβ GeV, with large muon g-2 contributions difficult and future colliders needed to cover the remaining parameter space.
