Diogo de Melo de Castro was the 11th & 13th Governor of Portuguese Ceylon. De Melo was first appointed in 1633 under Philip III of Portugal, he was Governor until 1635 and then in 1636 until 1638. He died in the Battle of Gannoruwa.

By the 1650s, the Portuguese had been in Ceylon for over 150 years, controlling the coastal regions and important cinnamon-producing areas. However, they were facing an existential threat from the Dutch East India Company (VOC), which was systematically capturing Portuguese territories in Asia. The Dutch wanted control of the lucrative spice trade, especially cinnamon, which grew abundantly in Ceylon.

Diogo de Melo de Castro arrived to govern during what turned out to be the final years of Portuguese control. Despite his efforts to defend the remaining Portuguese strongholds, he was ultimately fighting a losing battle. The Dutch had superior naval power and more resources, and they were gradually strangling Portuguese positions through blockades and military pressure.

His governorship ended in 1655, and just three years later, in 1658, the Portuguese lost their last major stronghold in Ceylon when the city of Jaffna fell to the Dutch. This marked the complete end of Portuguese rule on the island after about 150 years of colonial presence.
