Empress Kezuhun (可足渾皇后, personal name unknown) was an empress of the Chinese/Xianbei state Former Yan. Her husband was Murong Wei (Emperor You), the last emperor of the state.
She was the daughter of Kezuhun Yi (可足渾翼), the cousin of Murong Wei's mother Empress Dowager Kezuhun. Perhaps by her order, Murong Wei married her as empress in 369. There was no further historical record of her, although presumably she was relocated to the Former Qin capital Chang'an in 370 when Former Qin destroyed Former Yan. It is not known whether she survived to 385, when her husband was executed by Former Qin in light of his attempt to join his brother Murong Chong in rebellion.
