A Mud Brick Wall is a decorative wall variant made from Mud Bricks, featuring an earthy, brown-toned texture that fits well in rustic and desert-themed builds. It connects seamlessly with other walls, fences, and solid blocks, making it useful for enclosures and architectural details. Mud Brick Walls can be mined with any pickaxe; otherwise, they drop nothing.

They naturally generate in trail ruins and can be crafted using Mud Bricks or obtained through stonecutting. Like other walls, Mud Brick Walls can be placed under a note block to produce a bass drum sound.
