A zebroid is the offspring of any cross between a zebra and any other equine to create a hybrid. In most cases, the sire is a zebra stallion but not every time. The offspring of a donkey sire and zebra dam, called a donkra, and the offspring of a horse sire and a zebra dam, called a hebra, do exist, but are rare and are usually sterile. Zebroids have been bred since the 19th century. Charles Darwin noted several zebra hybrids in his works.

==Types== Zebroid is the term generally used for all zebra hybrids. The different hybrids are generally named using a portmanteau of the sire's name and the dam's name. Generally, no distinction is made as to which zebra species is used. Many times, when zebras are crossbred, they develop some form of dwarfism. Breeding of different branches of the equine family, which does not occur in the wild, generally results in sterile offspring. The combination of sire and dam also affects the offspring phenotype.
