* A large portion of the plot in Orson Scott Card's ''Pathfinder'' revolves around one of these. It's revealed decently early on that there are actually 19 "worlds" with Walls.

* There's one of these in GarthNix's ''OldKingdom'' books, separating the nonmagical land of Ancelstierre from the Old Kingdom, where there's necromancy and other magic. It's actually an artefact containing one of the five CosmicKeystone bloodlines that keeps [[FunctionalMagic the Charter]] together and is designed to keep anything nasty inside the Old Kingdom where people know how to deal with it. It's only moderately successful, hence the massive trench and bunker network on the Ancelstierran side.

** In ''So Long and Thanks for All the Fish'', Wonko the Sane constructs a wall around his home to fence in the world, which he calls "the Asylum." (He'd decided the entire world had gone insane when he came upon a pack of toothpicks with [[ViewersAreMorons instructions]].)
*** It wasn't a wall. He decided that the world was insane, and needed a safe place to be kept, so he constructed his house ''inside out'', and lived 'outside the Asylum', since the world was inside it.

** Not to forget the glass dome enclosing Springfield in TheMovie.
*** Or the wall made of garbage seperating Springfield from New Springfield.

* A variety occurs in ''AngelBeats''. There's no literal wall, but nobody seems to know what's beyond the hills surrounding the high school complex.

* [[TheLegendOfZelda The Legend of Zelda: Wind Waker]]): The Great Sea has no physical barrier to keep you from leaving the map. However, your boat tells you that it's dangerous to leave and turns you around.

* The wall separating Experiment House property from Narnia in TheSilverChair.

The wall can surround a single village, a town, a continent, a world, or even [[CorralledCosmos an entire galaxy]]. Or it could seemingly surround nothing, and simply mark a barrier between one world and the next.

* Ba Sing Se, the Earth Kingdom capital in ''[=~Avatar: The Last Airbender~=]'', is both surrounded by a giant wall and built in the middle of a desert.

* The Israeli containment wall around the Palestinian territories is a partial example. Palestinians CAN pass through it, albeit after going through the proper security clearances/checkpoints. Likewise, those in the West Bank could potentially go to Jordon, but the Egyptians close their borders to the Gazans (considering that Hamas is ruling the Gaza strip, no one wonders why).
* [[CrapsackWorld North Korea]].

* Notably subverted in TheThirteenthFloor, where the world has no physical wall around it but it does have an edge where the simulated nature is visible to the naked eye. People with in the simulated world are just programmed to never think about going anywhere near that edge (of course there are exceptions...)
