In Minecraft, there are two types of biomes in which Armadillos naturally spawn. The first of these is the trio of Badlands biomes. This includes the regular Badlands biomes, as well as the Eroded and Wooded Badlands.

The second type of biome they will spawn in is the Savanna. They will spawn in regular Savannas, Savanna Plateaus, and Windswept Savannas. I had the most luck in a Savanna Plateau, where I found a small family of four Armadillos.
