The Osaka Kintetsu Buffaloes (大阪近鉄バファローズ, Ōsaka Kintetsu Bafarōzu?) was a Nippon Professional Baseball team based in Osaka, Japan, which were in the Pacific League. The team was owned by Kinki Nippon Railway Co. (later: Kintetsu Corp.) and later sold to the Orix Group, the owner of the Orix BlueWave baseball team, in 2004. The new owner then announced that they would merged the two teams into one team called the Orix Buffaloes before the start of the 2004-2005 NPB season.
