Motivations for expecting supersymmetry to appear at energies ≳1 TeV are reviewed, and it is emphasized that the lightest supersymmetric particle is an ideal candidate for cold dark matter. Experimental and cosmological constraints on supersymmetric dark matter are reviewed, and the prospects for indirect or direct detection are discussed. Finally, the potential implications of a Higgs boson weighing about 115 GeV are summarized. ©2001 American Institute of Physics.
