This document describes a search for lepton flavor violation (LFV) in the bottomonium system. Using the data collected with the CLEO III detector, we looked for the leptonic decays Upsilon(nS) -> mu + tau (where n = 1, 2, and 3). The tau lepton was identified through its leptonic decay to an electron, and signal yields were obtained through multidimensional likelihood fitting with probability density function shapes measured from independent data samples. No signal was observed. Therefore, we report our results as upper limits on the LFV branching fractions of Upsilon mesons at the 95% confidence level.
