We consider the flavor-diagonal neutrino-two-photon vertex in the standard model. Whereas for massless neutrinos this vertex is of order GFαpν/m2W, for massive neutrinos a contribution to this amplitude of order GFαmν/m2e is identified and calculated. This contribution can be thought of as arising from a triangle graph containing electrons. The neutrino-two-photon vertex also gets a significant contribution from a second-order effect if the electromagnetic moments are anomalously large, as recently proposed to solve the solar-neutrino problem. The effects of the neutrino-two-photon vertex on neutrino-photon scattering and on photon pair annihilation into neutrinos are calculated for situations that may be of astrophysical or cosmological interest. The long-range force between a neutrino and a charge arising from two-photon exchange is also discussed.
