  Recently, gamma-ray emission in the direction of Coma, with a TS value of
$\sim 40$, has been reported. In this work we will discuss the possibility of
such a residual emission coming from dark matter annihilation. Our results show
that the gamma-ray emission within the Coma region is also spatially correlated
to the mass distribution derived from weak gravitational lensing measurements
very well. However the dark matter models are not supported by the spectral
analysis results and constraints by observations of other targets. Thus we
derive the upper limits of the dark matter annihilation cross section according
to the observation of the Coma region.
