I will review the physics of neutrinos from core collapse
supernovae, with highlights of recent advances in this field. Emphasis will be placed on how to improve the theory of neutrino emission and propagation, and on the physics potential of the next generation ofneutrino detectors. Different regimes will be discussed, ranging from a very high statistics observation of a nearby supernova, to the quasi-diffuse or diffuse flux detection from several very distant collapsing stars. New directions involving multi-messenger observations of supernovae (with neutrinos, photons and gravitational
waves) will be presented.
