There is a possible \gamma-ray signal at 130 GeV coming from the GalacticCenter as seen by Fermi-LAT experiment. We give a SUSY dark matter model toexplain this \gamma-ray feature in NMSSM. We show that in NMSSM, one can have abenchmark set in which the \gamma-ray signal arises from final state \gamma'sin the $\chi\chi \to f \bar f \gamma $ annihilation of a 130 GeV bino darkmatter requiring a boost factor of ~590 to fit the \gamma-ray signal. Inaddition, this benchmark set also gives the correct relic density, lightestHiggs mass of 125 GeV and is consistent with constraints on SUSY from LHC. Thisdark matter model evades the XENON100 constraint but is testable in a futureXENON1T experiment.
