Abstract: In this talk I will present some unique opportunities that a high-energy muon collider offers in answering key neutrino-related questions. There is a community effort trying to identify questions that cannot be addressed by current or near-future experiments, with an emphasis on exploring new physics through neutrino interactions at such a collider. I will summarize some benchmark physics cases within the SM and beyond that have been studied in the recent years. In addition, I will show the results of the fluxes of neutrinos of all flavors produced in primary $\mu^+\mu^-$ collisions, electromagnetic showers induced by electrons from muon decay, and interactions of neutrinos close to the collider ring. These additional sources are not negligible and lead to a sizable number of neutrino interactions of all flavors, including a few hundred tau neutrinos, in a ton-scale detector placed in the forward direction. I will discuss the opportunities opened by these results for tau-neutrino measurements, as well as the implications for BSM searches associated with the appearance of tau neutrinos.
