Dragon's Nest is a stage in Tekken 5. A long, concrete dragon clutching an egg in one of its paws surrounds the arena and the fighters. Some boulders and concrete flames are in some parts of the stage, as well. Another concrete dragon can be seen surrounding a mountain that is far away.

This would possibly be Feng Wei's stage.

The characters that have inteludes in this stage are

• Wang Jinrei
• Baek Doo San
• Hwoarang
• Roger Jr.
• Mokujin
