World 3- is the Ghost House and the fourth level of World 3 in Another Super Mario Bros. Wii.

World 3- is unlocked by completing World 3-2. Completing its normal exit will unlock a shortcut to World 3-, and completing its secret exit will unlock World 3-. Alternatively, World 3- can be accessed through a shortcut by completing World 3-3, though it would have already been unlocked through the completion of World 3-2.
