The Battle of Formoso River of 1615 was a naval battle that took place in the Malay Peninsula in the Formoso River, between a Portuguese fleet and a large fleet of the Sultanate of Aceh, one of the largest Aceh had ever mobilized against the Portuguese in Malacca.
In what was "one of the bloodiest battles the Portuguese fought in south-east Asia", the Acehnese suffered so much damage they were forced to call off their plans to attack Malacca and returned to Aceh.
