A zombie horse is an undead variant of the horse. It rarely spawns in dark areas as a hostile mob being ridden and controlled by a zombie horseman wielding an iron spear. It becomes passive once separated from the zombie rider.

Zombie horses can naturally spawn on grass blocks in savanna, savanna plateau, windswept savanna, plains, sunflower plains, and snowy plains biomes as zombie horsemen: a zombie wielding an iron spear riding a zombie horse. Like zombies themselves, zombie horsemen can only spawn at a light level of 0‌[Java Edition only], or light levels below 7‌[Bedrock Edition only][1], both above ground and underground. They will also burn in daylight. However, due to the lack of grass blocks underground in the Overworld, they are mostly found on the surface. The zombie horse never spawns as a baby. Other zombie variants such as husks and zombie villagers cannot spawn as horsemen. In Bedrock Edition, zombie horses are programmed to spawn in ice spikes biomes, but they fail to do so naturally, as the biome's surface is made of snow blocks instead of grass blocks, meaning they also cannot spawn underground in that biome.
