The Sultanate of Asahan was a Malay sultanate from approximately 1630 AD until 1946 AD. It was located in the north-east of the island of Sumatra, in what is now Indonesia and covered what is now the Asahan Regency.

Iskandar Muda was the twelfth Sultan of Acèh Darussalam, under whom the sultanate achieved its greatest territorial extent, holding sway as the strongest power and wealthiest state in the western Indonesian archipelago and the Strait of Malacca. "Iskandar Muda" literally means "young Alexander," and his conquests were often compared to those of Alexander the Great. In addition to his notable conquests, during his reign, Aceh became known as an international centre of Islamic learning and trade. He was the last Sultan of Aceh who was a direct lineal male descendant of Ali Mughayat Syah, the founder of the Aceh Sultanate. Iskandar Muda's death meant that the founding dynasty of the Aceh Sultanate, the House of Meukuta Alam died out and was replaced by another dynasty.
