We make an evaluation of the lepton flavor violating (LFV) decays $\tau \to\ell (V^0, P^0)$, where $\ell=e$ or $\mu$ and $V^0(P^0)$ is a neutral vector(pseudo-scalar) meson, in the context of unparticle physics. The constraintsare investigated systematically on the related coupling parameters from all theavailable experimental data, and the parameter values are specifiedappropriately. The results show that whereas over the whole parameter spaceallowed by experiments all the $\tau \to \ell P^0$ modes have a branching ratiotoo small to be measurable experimentally, in a large subspace as observed allof the $\tau \to \ell V^0$ modes get simultaneously a branching ratio as highas ${\cal O}(10^{-10}-10^{-8})$, which is reachable at the LHC and super Bfactory. The important implications are drawn.
