We have searched for lepton flavor violating decays of a $\tau$ to a lighter-mass charged lepton and an $\omega$ vector meson
using 384.1 $fb^{-}$ of $e^+e^- $ 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 ${\cal B}(\tau^{\pm} \rightarrow \mathrm{e}^{\pm} \omega) < 1.1\times10^{-7}$ and
${\cal B}(\tau^{\pm} \rightarrow \mu^{\pm} \omega) < 1.0\times10^{-7}$ at 90\% confidence level.
