Recent experimental results in direct dark matter detection may be interpreted in terms of a dark matter particle of mass around 10 GeV/c2. We show that the required scenario can be realized with a new dark matter particle charged under an extra Abelian gauge boson Z^\ensuremath' that couples to quarks but not leptons. This is possible provided the Z^\ensuremath' gauge boson is very light, around 10--20 GeV/c2 in mass, and the gauge coupling constant is small, \ensuremathα^\ensuremath'\ensuremath∼10^\ensuremath-5. Such scenarios are not constrained by accelerator data.
