  Neutron stars are efficient accelerators for bringing charges up to
relativistic energies. We show that if positive ions are accelerated to ~1 PeV
near the surface of a young neutron star (t_age < about 10^5 yr), protons
interacting with the star's radiation field will produce beamed mu neutrinos
with energies of ~50 TeV that could produce the brightest neutrino sources at
these energies yet proposed. These neutrinos would be coincident with the radio
beam, so that if the star is detected as a radio pulsar, the neutrino beam will
sweep the Earth; the star would be a ``neutrino pulsar''. Looking for muon
neutrino emission from young neutron stars will provide a valuable probe of the
energetics of the neutron star magnetosphere.
