Mindoro Strait is a strait in the Philippines, separating Mindoro Island from Busuanga Island (Calamian Islands) of Palawan. Located within its waters is the Apo Reef, the largest coral reef system in the Philippines.
The Mindoro Strait is part of an alternate route for large ships going to and from the Indian Ocean to the Pacific. These are ships larger than the Malaccamax size and therefore cannot pass through the Strait of Malacca.
