The Hogwarts Thestral herd was a herd of Thestrals employed at Hogwarts School of Witchcraft and Wizardry. They lived in the Forbidden Forest, specifically in the Thestral Paddock. The herd started out with one male and five females, with Tenebrus as the first to be bred in the forest. The Gamekeeper Rubeus Hagrid bred, trained, and cared for the creatures. They were mainly used to pull the Hogwarts carriages up to the school from Hogsmeade Station to the Entrance Gates for Second through Seventh year students, although they were sometimes used by Albus Dumbledore when he went on a long journey and didn't want to Apparate. These Thestrals were trained to go to anywhere they are told by a rider due to their impeccable sense of direction. They were also trained not to attack owls so as not to interfere with the owl post. Hagrid reckoned that the herd was the only tamed herd of its size in Great Britain.

The herd also took part in the Battle of Hogwarts, where they attacked the Death Eaters and Voldemort's giant allies.
