  We investigate the possibility of the Z3 scalar singlet model explaining the
Fermi galactic centre excess. We find a good fit to the measured spectral
excess in the region where the dark matter mass is comparable to the Higgs and
the Higgs portal coupling $\lambda_{HS}\sim 0.04$. This preferred region is
consistent with constraints from vacuum stability and current dark matter
experiments, and will be discovered or falsified soon by future dark matter
direct detection experiment.
