  As cosmology has entered a phase of precision experiments, the content of the
universe has been established to contain interesting and not yet fully
understood components, namely dark energy and dark matter. While the cause and
exact nature of the dark energy remains mysterious, there is greater hope to
connect the dark matter to current models of particle physics. Supersymmetric
models provide several excellent candidates for dark matter, with the lightest
neutralino the prime example. This and other dark matter candidates are
discussed, and prospects for their detection summarized. Some methods of
detection are explained, and indications of signals in present data are
critically examined.
