Hamdan ibn Hamdun ibn al-Harith al-Taghlibi (fl. 868–895) was a Taghlibi Arab chieftain in the Jazira, and the patriarch of the Hamdanid dynasty. Alongside other Arab chieftains of the area, he resisted the attempts at re-imposition of Abbasid control over the Jazira in the 880s, and joined the Kharijite Rebellion. He was finally defeated and captured by Caliph al-Mu'tadid in 895, but was later released as a reward for the distinguished services of his son Husayn to the Caliph.
