  I will begin by reviewing the evidence for Dark Matter in the Universe, as
well as the candidates for dark matter. At most 20% of the dark matter in
galaxies can be in the form of MACHOs (Massive Compact Halo Objects); the
remainder appears to be some unknown exotic component. The most sensible
candidates from the point of view of particle physics are axions and WIMPs
(Weakly Interacting Massive Particles), where WIMPs may be supersymmetric
particles. Three recent claims of possible detection of WIMP dark matter are
tantalizing and will be discussed: the DAMA annual modulation, the HEAT
positron excess, and gamma-rays from the Galactic Center. In addition, I will
discuss the dependence of signals in detectors on the mass distribution in the
Galactic Halo. In particular, the Sagittarius stream can be a smoking gun for
WIMP detection.
