A Skeleton Horseman is a type of undead miniboss found in Minecraft Dungeons.

Spawning
Skeleton Horsemen spawn on Adventure mode and above, and spawns randomly in groups in Creeper Woods, Soggy Swamp, Pumpkin Pastures, Cacti Canyon, Redstone Mines, Desert Temple, and the Overgrown Temple. In Apocalypse difficulty, they also spawn in Fiery Forge. They can also be found early on default mode uncommonly at Cacti Canyon.
