The detection of high-energy cosmic neutrinos and their astrophysical interpretation has been a vision for decades, motivating detectors of
ever increasing size and sensitivity. Since 2013 the vision is reality: Neutrinos of cosmic origin in the energy range between some 10 TeV and some PeV have unambiguously be discovered with the IceCube detector in the deep South Polar ice. We now have to go the next step from this first glimpse at the neutrino sky to full-sky neutrino astronomy. This will require an upgrade of IceCube, but in particular also a neutrino telescope in the Nothern hemisphere: KM3NeT, a cubic-kilometre-scale future neutrino telescope in the deep Mediterranean Sea. KM3NeT builds on the experience with the ANTARES detector; it will investigate neutrinos of cosmic origin and also use the exact same technology to determine the neutrino mass hierarchy from precision measurements of atmospheric neutrino oscillations. I will present the IceCube and KM3NeT detectors, report on the status of cosmic neutrino measurements and the performance of the first KM3NeT detector modules in operation, and discuss the physics reach of KM3NeT and the future IceCube-Gen2.
