  GRBs are the most energetic events in the Universe, associated with the death
of massive stars (core-collapse supernovae) or the merging of neutron stars or
black holes. Discovered in the early 1970s, their cosmological origin was
demonstrated only in 1997, when the first distance was measured. Theoretical
models predict that the very energetic processes at work in GRBs accelerate
charged particles to such energies that they could contribute to the observed
high energy neutrinos.
  These processes will be discussed and the observational consequences, in
particular for current and forthcoming neutrino telescopes, presented.
