The Undergrounds (also known as the Dirt Biome) is the biome that the player first spawns in. It is a low difficulty area meant to teach a player the game's mechanics; enemies here are slow and predictable.

The biome is made up of Dirt, Turf and Sand Blocks, soft enough to break with the player's hands or a weak pickaxe. Rivers and lakes of normal water are common.

The Undergrounds generates at a distance of 0–150 tiles from The Core, in a rough circular shape. Small patches of the Meadow sub-biome may generate within it.
