A search for lepton flavor violating decays of a {tau} to a lighter-mass charged lepton and an {omega} vector meson is performed using 384.1 fb{sup -1} of e{sup +}e{sup -} annihilation data collected with the BABAR detector at the Stanford Linear Accelerator Center PEP-II storage ring. No signal is found, and the upper limits on the branching ratios are determined to be B({tau}{sup {+-}}{yields}e{sup {+-}}{omega})<1.1x10{sup -7} and B({tau}{sup {+-}}{yields}{mu}{sup {+-}}{omega})<1.0x10{sup -7} at 90% confidence level.
