  Cosmology now provides unambiguous, quantitative evidence for new particle
physics. I discuss the implications of cosmology for supersymmetry and vice
versa. Topics include: motivations for supersymmetry; supersymmetry breaking;
dark energy; freeze out and WIMPs; neutralino dark matter; cosmologically
preferred regions of minimal supergravity; direct and indirect detection of
neutralinos; the DAMA and HEAT signals; inflation and reheating; gravitino dark
matter; Big Bang nucleosynthesis; and the cosmic microwave background. I
conclude with speculations about the prospects for a microscopic description of
the dark universe, stressing the necessity of diverse experiments on both sides
of the particle physics/cosmology interface.
