Dark matter may be composed of superWIMPs,
superweakly-interacting massive particles produced in the late decays of
other particles.  Well-motivated examples are gravitinos in supersymmetry
and Kaluza-Klein gravitons in universal extra dimensions.  Such particles
are produced after a year, and so seemingly tightly constrained by BBN.
I show that this dark matter candidate is nevertheless viable, and explore
its implications for BBN, the CMB, and collider searches for new physics.
In such a scenario, the gravitational interactions of individual
fundamental particles may be explored experimentally.
