To study the production mechanism of heavy quarkonium (e.g. J/\Psi) is extremely important for the ongoing research at the Relativistic Heavy Ion Collider (RHIC), where this process is playing an important role in the search for Quark-Gluon Plasma (QGP) from heavy ion collisions, as well as for the investigation of the proton spin structure. The Pioneering High Energy Nuclear Interaction eXperiment (PHENIX) is one of the largest experiments at RHIC. In this talk, a measurement of J/\Psi polarization at 200 GeV proton+proton collisions with the PHENIX muon arm detectors at RHIC will be presented. The results from the current data show no polarization within the PHENIX acceptance range. The results are consistent with the current model predictions and other experimental measurements.
