Shipping container walls are defensive walls, great walls, or other fortifications built largely out of shipping containers. These types of fortifications are often seen in post-apocalyptic worlds or wastelands where they may surround post-apocalyptic havens or forts. They may also be built on the borders of quarantine zones to help contain the infected or on the frontier to defend against raiders.

Just as with more normal defensive walls, fictional shipping container walls may have elements like gatehouses, watchtowers, and drawbridges. These elements are typically altered or reskinned to better fit with the shipping container aesthetic. There may be scaffolding on the inner side of the wall to allow people or guards to better defend the ramparts.

Sneaking through a wall is a common narrative event. Fictional shipping container walls may possess hidden doors, secret passageways through them, or underground tunnels underneath.
