  This is the writeup of the lectures on neutrino physics delivered at various
schools: TASI and Trieste in 2013 and the CERN-Latin American School in 2015.
The topics discussed in this lecture include: general properties of neutrinos
in the SM, the theory of neutrino masses and mixings (Dirac and Majorana),
neutrino oscillations both in vacuum and in matter, as well as an overview of
the experimental evidence for neutrino masses and of the prospects in neutrino
oscillation physics. We also briefly review the relevance of neutrinos in
leptogenesis and in beyond-the-Standard-Model physics.
