After more than a decade since the advent of neutrino astronomy, the origin of most of the diffuse astrophysical neutrino flux observed by IceCube remains unresolved. Notably, while IceCube has yet to detect any neutrino events above 10 PeV, the KM3NeT collaboration has recently reported the observation of the highest-energy neutrino ever detected. Ultra-high-energy (UHE) neutrinos (E > 10 PeV) are expected to originate either directly from astrophysical sources or as cosmogenic neutrinos produced during the propagation of ultra-high-energy cosmic rays interacting with cosmic photon fields. Because of their extremely low flux, detecting such particles requires detectors covering surfaces of the order of hundreds of square kilometers. In this talk, I will discuss the scientific importance of UHE neutrino detection, together with an overview of current and future experimental efforts aiming to unveil these elusive messengers.
