We investigate the potential of eγ collisions to probe anomalous Wtb couplings via the polarized single top quark production process e+γ→tb̄νē. We find 95% confidence level limits on the anomalous coupling parameters F2L and F2R with an integrated luminosity of 500 fb-1 and , 1 and 1.5 TeV energies. The effects of top quark spin polarization on the anomalous Wtb couplings are discussed. It is shown that polarization leads to a considerable improvement in the sensitivity limits.
