Neutrinos are the only hint for physics beyond the Standard Model. While the hierarchy problem, gauge coupling unification and dark matter give rise to hope for a direct discovery of new physics at the LHC, Occam's razor suggests that there might be a relation. In this talk I discuss 3.5 frontiers, where neutrino physics might be directly related to new physics to be discovered in the unknown realm of the Terascale:

• the Majorana frontier
• the Unification frontier
• the Flavor frontier
• the Exotics frontier
