Hachiun (Mongolian: Хачиун), also known as Hachiun Alchi (Mongolian: Хачиун Алчи) was a full-brother of Genghis Khan and third son of Hoelun. His father was Yesügei Baghatur.
Hachiun was said to have a very good relationship with his brother Hasar but a poorer one with Temüge. This might be due to preferential treatment of his younger brother in the form of land and power. Of all the brothers he had the firmest relationship with Genghis.
