  We present a simple extension of the standard model that gives rise to
baryogenesis a has a dark matter candidate of O(GeV) mass. A minimal set of new
fields required for baryogenesis includes two O(TeV) colored scalars and a
singlet fermion. The fermion also becomes a viable dark matter candidate when
its is nearly degenerate in mass with the proton. Dark matter and baryon
asymmetry are produced form the decay of heavy scalars, which can lead to a
natural explanation of the baryon-dark matter coincidence problem. The dark
matter candidate escapes direct and indirect detection, but can be probed at
the LHC. The supersymmetric extension of this model is straightforward and
leads to a multi-component dark matter scenario, which improves the direct and
indirect detection prospects.
