The Sultanate of Deli (Indonesian: Kesultanan Deli Darul Maimoon; Jawi: كسلطانن دلي دارالميمون‎) was a 1,820 km2 Malay state in east Sumatra founded in 1632 when a commander of the Aceh Sultanate, Gocah Pahlawan, conquered the area during the reign of Iskandar Muda. A tributary kingdom from 1630 it was controlled by various sultanates until 1814, when it became independent and broke away from the Sultanate of Siak.

Dutch intervention in the mid-19th century resulted in a 1862 contract with the Dutch East Indies, which helped to recognise Deli's formal independence from Aceh and Siak. After Indonesian independence, the sultanate ceased to hold formal political authority. However, the sultanate remains a lasting symbol of the history of Medan.
