We calculated the polarization of \psi- due to gg \to Q\bar{Q}^3P J^(8)g \to \psi^\lambda color-octet quarkonia production. We find that at low transverse momenta the \psi- is unpolarized due to the contributions proportional to the L=S=0 and L=S=1 color-octet matrix elements. As p \perp increases, the \psi- mesons become 100% polarized, as predict
