The Antarctic Muon and Neutrino Detector Array (AMANDA) has been searching the heavens for astrophysical neutrinos (from both diffuse and discrete sources) since 1997. Among the potential neutrino sources are Active Galactic Nuclei, topological defects, WIMPs, SGR flares, and Gamma-Ray Bursts (GRBs). Working in concert with other ground- and space-based observatories (such as the satellites of the Third InterPlanetary Network), AMANDA has searched for approxmiately 500 GRBs during its entire lifetime; here we present the cumulative results from the first two stages of the AMANDA detector (from 1997 to 1999 and from 2000 to 2003). Because of the precise timing and location information derived from photon observations, AMANDA's search is nearly background-free. The minimal selection criteria necessary for this search afford the detector with an enormous neutrino collecting area; thus, the flux limits for GRB neutrino predictions are the most stringent available to date. The implications of these results for various theoretical models are discussed, and the discovery potential for current and future neutrino detectors in the era of Swift is briefly treated.
