The siege of Aru was a military campaign carried out by the Johor Sultanate in April and May 1540, aimed at retaking the Aru Kingdom from the Aceh Sultanate. The campaign involved a coalition of Johor forces, Aru rebels, and Portuguese troops from Malacca. The siege formed part of the larger Johor–Aceh conflict and culminated in the temporary restoration of Aru under Johor's influence.
