In this talk I will review various theoretical and phenomenological aspects of massive neutrinos. After a brief review of conventional approaches for neutrino masses, I will focus on a systematic classification of the so-called Weinberg operator. I will comment as well on the connection between neutrino mass generation and the generation of the baryon asymmetry of the universe.
