They both have no electromagnetic charge. Also, the photon is massless, and for a long time the neutrino was also thought to be massless.
In the early days of applying supersymmetry to the real world, these similarities motivated an attempt to treat the neutrino as the superpartner of the photon. (But this was soon abandoned.)
