We assess the extent to which the NMSSM can allow for light dark matter in the $$2\gev\lsim \mcnone\lsim 12\gev$$ mass range with correct relic density and large spin-independent direct-detection cross section, $$\sigsi$$, in the range suggested by \cogent\ and DAMA. For standard assumptions regarding nucleon $$s$$-quark content and cosmological relic density, $$\rho$$, we find that the NMSSM falls short by a factor of about 10 to 15 (3 to 5) without (with) significant violation of the current $$(g-2)_\mu$$ constraints.
