The data were recorded with the BaBar detector at the PEP-II asymmetric-energy B-meson Factory at SLAC and correspond to 89 million B B-bar pairs produced in e+e- annihilation at the Upsilon(4S) resonance. We find no evidence for a signal and set a 90% CL upper limit of BF(B0 -> eta' phi) < 1.0 x 10^-612 pages, 2 postscript figures, Contributed to the XXI International Symposium on Lepton and Photon Interactions at High Energies, 8/11 - 8/16/2003, Fermilab, Illinois USAHigh Energy Physics - Experimenttext
