The Kathiri State of Seiyun was a sultanate in the Hadhramaut region of southern Arabia, established in 1379. At times it ruled a wide area from Dhofar to the Empty Quarter, but later lost much of it to the Qu'aiti. It joined the British Protectorate of South Arabia and was absorbed into South Yemen in 1967.
