A zebroid is the offspring between a zebra and any other equine to create a hybrid. In most cases, the sire is a zebra stallion.

The zorse is one of a number of equine hybrids that are known as zebroids. It is generally the result of cross-breeding a male zebra (stallion) with a female horse (mare) to produce an animal that looks more like a horse than a zebra, but one that has stripes.

In Africa, zebras and horses are often crossbred to create zorses that are used as trekking animals to transport both people and goods up and down the mountains.

The zebra part gives the zorse resistance to certain pests and diseases that normally affect horses but not zebras. The animal can vary dramatically particularly in size and color, depending on its parents. A pattern of bold stripes is also unique to each animal, meaning that they can be easily distinguished between one another. Like most other animal hybrids, the zorse is sterile.

The much rarer reverse pairing between a female zebra and a horse stallion is sometimes called a hebra. An offspring between a zebra and a donkey is known as a zonkey.
