The Battle of Duyon River was a naval engagement between the Portuguese forces commanded by Nuno Álvares Botelho, who is renowned in Portugal as one of the last great commanders of Portuguese India, and the forces of the Sultanate of Aceh, which were led by the Laksamana.

The relatively modest Portuguese fleet achieved an absolute victory over the Ottoman-allied Aceh in that not a single ship or man of the invading force sent to conquer Malacca returned to their country. The Sultanate of Perak, a vassal of the Sultanate of Aceh, defected to the Portuguese side after the battle.
