  We propose a simple scenario that directly connects the dark matter (DM) and
neutrino mass scales. Based on an interaction between the DM particle $\chi$
and the neutrino $\nu$ of the form $\chi\chi\nu\nu/\Lambda^2$, the DM
annihilation cross section into the neutrino is determined and a neutrino mass
is radiatively induced. Using the observed neutrino mass scale and the DM relic
density, the DM mass and the effective scale $\Lambda$ are found to be of the
order MeV and GeV, respectively. We construct an ultraviolet-complete toy model
based on the inverse seesaw mechanism which realizes this potential connection
between DM and neutrino physics.
