In this talk I will discuss both neutrinos directly coming from astrophysical sources and neutrinos produced by ultra-high energy (UHE) protons in interactions with the cosmic microwave background radiation. I will also consider possible neutrino fluxes in several exotic UHE cosmic ray models and fluxes from individual sources. I will show that in a variety of cases the diffuse neutrino flux can be considerably higher than the earlier theoretical estimates. High neutrino fluxes would significantly increase the chances to detect UHE neutrinos with experiments currently under construction or in the proposal stage.
