Abstract: An upper limit on the masses of scalar superpartners in split supersymmetry is found by considering cosmological constraints on long-lived gluinos. Over most of parameter space, the most stringent constraint comes from big bang nucleosynthesis. A TeV-mass gluino must have a lifetime of less than 100 seconds to avoid altering the abundances of D and $^{6}\mathrm{L}\mathrm{i}$. This sets an upper limit on the supersymmetry breaking scale ${m}_{S}$ of ${10}^{9}$ GeV.
