The overview of the spin physics at RHIC-PHENIX experiment
  In Spiring 2005, RHIC successfully completed its first long data collection run with polarized proton beams. PHENIX accumulated ten fold larger statistics with higher polarization than the previous spin physics run in 2003. This contribution will introduce the RHIC-PHENIX experiment and present our recent results.
