  A model for high-energy (>10^14 eV) cosmic rays (HECRs) from galactic and
extragalactic gamma-ray bursts (GRBs) is summarized. Relativistic outflows in
GRBs are assumed to inject power-law distributions of CR protons and ions to
the highest (>10^20 eV) energies. A diffusive propagation model for HECRs from
a single recent GRB within 1 kpc from Earth explains the CR spectrum near and
above the knee. The CR spectrum at energies above 10^18 eV is fit with a
component from extragalactic GRBs. By normalizing the energy injection rate to
that required to produce the CR flux from extragalactic sources observed
locally, we determine the amount of energy a typical GRB must release in the
form of nonthermal hadrons. Our interpretation of the HECR spectrum requires
that GRBs are hadronically dominated, which would be confirmed by the detection
of HE neutrinos from GRBs.
