A Bonus Land (also known as a Bonus Room or Bonus Level) is a hidden area in the [[Mario (series)|Mario] series of games; particularly the Super Mario Bros and Super Mario Bros: The Lost Levels games.
Bonus Areas are usually revealed by finding either a secret passage or by jumping into a Warp Pipe. In Bonus Areas, there's almost always a prize of some nature. In Super Mario World, there's a warp pipe that takes you to the bonus areas.
