We treat high-energy neutrino production in gamma ray bursts (GRBs). Detailed calculations of photomeson neutrino production are presented for the collapsar model, where internal nonthermal synchrotron radiation is the primary target photon field, and the supranova model, where external pulsar-wind synchrotron radiation provides important additional target photons. Detection of greater than or similar to10 TeV neutrinos from GRBs with Doppler factors greater than or similar to200, inferred from gamma-ray observations, would support the supranova model. Detection of less than or similar to10 TeV neutrinos is possible for neutrinos formed from nuclear production. Only the most powerful bursts at fluence levels greater than or similar to3x10(-4) erg cm(-2) offer a realistic prospect for detection of nu(mu).
