'''World B-1''' is the first level of [[World B]] in ''[[Super Mario Bros.: The Lost Levels]]'' and the ninth secret level overall in said game.

==Layout==
The player starts facing a couple of [[Goomba]]s and a [[Koopa Troopa]] below a row of [[? Block]]s. Between the two pipes with [[Piranha Plant]]s and another Koopa Troopa is a [[Hidden Block]] with a [[1-Up Mushroom]], and in the right-most block in the row of [[Brick Block]]s ahead is a [[Coin Block]]. In the right-most ? Block above two [[Koopa Paratroopa]]s is a power-up. To reach a [[Beanstalk]] that leads to [[Coin Heaven]], the player has to hit two Hidden Blocks directly to the right of the pipe with a Piranha Plant, and break the Brick Blocks while in [[Super Mario (form)|Super]] form. Coin Heaven will drop the player directly after the pipe on top of ? Blocks positioned afterward. In the center of the top row of Brick Blocks is a [[Super Star]], and in the right-most ? Block after the [[Super Spring]] ([[Springboard]] in ''[[Super Mario All-Stars|All-Stars]]'') is a power-up. In the center ? Block afterward is a [[Poison Mushroom]], and after platforms with Koopa Troopas, Koopa Paratroopas, Piranha Plants, and Goombas is the [[Goal Pole]].
