We study the effects of unparticle physics on muon g-2 and lepton flavor violating (LFV) tau decay processes. LFV interactions between the standard model sector and unparticles can explain the difference of the experimental value of muon g-2 from the standard model prediction. While the same couplings generate LFV tau decay, we found that LFV coupling can be of O(0.1...1) without conflict with the experimental bounds of LFV tau decay if the scaling dimension of unparticle operator d{sub U} > or approx. 1.6.
