The Žemaitukas is a historic pony breed from Lithuania. Known from the 6–7th centuries it was used as a war horse by the Lithuanians during the Northern Crusades and is hailed in Lithuania as part of the state's historic heritage. Its origin is uncertain but it is related to indigenous forest horse breeds and the Konik a Polish breed which were both probably descended from the Tarpan. The breed contributed to the foundation of the Trakehner.
