The recent discovery of high-energy astrophysical neutrinos has opened a new window to the Universe. Identifying the sources of these neutrinos is the main focus of the emerging field of neutrino astronomy. Combining neutrino data and electromagnetic measurements in a multi-messenger approach may lead us to the sources of the neutrinos and help to solve the long-standing big question of the origin of high-energy cosmic rays. A leading candidate source population is active galaxies, which host accreting supermassive black holes and relativistic jets. In this talk I will review the current status of the field and what we know about the possible role of jetted AGN as sources of high-energy neutrinos.
