Neutrinos play a role in various aspects of cosmology, including production of light elements, and the rate of expansion of the universe. Furthermore, the neutrino masses imply the likely existence of right-handed neutrinos, which can exist in the form of dark matter, and which can explain the matterantimatter asymmetry of the universe. I will discuss the many faces ordinary and hypothetical neutrinos in cosmology.
