The 2.6 sigma deviation in the muon's anomalous magnetic moment has strong implications for supersymmetry. In the most model-independent analysis to date, we consider gaugino masses with arbitrary magnitude and phase, and sleptons with arbitrary masses and left-right mixings. For tan(beta)=50, we find that 1 sigma agreement requires at least one charged superpartner with mass below 570 GeV; at 2 sigma, this upper bound shifts to 850 GeV. The deviation is remarkably consistent with all constraints from colliders, dark matter, and b -> s gamma in supergravity models, but disfavors the characteristic gaugino mass relations of anomaly-mediation.
