  We propose that dark matter is composed of particles that naturally have the
correct thermal relic density, but have neither weak-scale masses nor weak
interactions. These WIMPless models emerge naturally from gauge-mediated
supersymmetry breaking, where they elegantly solve the dark matter problem. The
framework accommodates single or multiple component dark matter, dark matter
masses from 10 MeV to 10 TeV, and interaction strengths from gravitational to
strong. These candidates enhance many direct and indirect signals relative to
WIMPs and have qualitatively new implications for dark matter searches and
cosmological implications for colliders.
