  A complete model for the origin of high-energy >~10^{14} eV) cosmic rays from
gamma-ray bursts (GRBs) and implications of this hypothesis are described.
Detection of high-energy neutrinos from GRBs provide an unambiguous test of the
model. Evidence for cosmic-ray acceleration in GRBs is suggested by the
detection of anomalous gamma-ray components such as that observed from GRB
941017. Neutron beta-decay halos around star-forming galaxies such as the Milky
Way are formed as a consequence of this model. Cosmic rays from GRBs in the
Galaxy are unlikely to account for the ~10^{18} eV cosmic-ray excess reported
by the Sydney University Giant Air Shower Recorder (SUGAR), but could
contribute to past extinction events.
