The Verde Island Passage is a strait that separates the islands of Luzon and Mindoro in the Philippines, connecting the South China Sea with the Tayabas Bay and the Sibuyan Sea beyond. Traditionally, the sea lane has been one of the busiest in the Philippines because it acts as a corridor from the Port of Manila to the Visayas and Mindanao in the south. A network of ferry routes cross the passage and connect the surrounding provinces of Batangas, Marinduque, Occidental Mindoro, Oriental Mindoro and Romblon. The Verde Island Passage is identified as a site of highest marine biodiversity importance in the Coral Triangle. The 1.14 million hectare passage is extremely rich in marine biodiversity and has been called "Center of the Center of Marine Shorefish Biodiversity" with various conservation groups and local government units pushing for its nomination as a UNESCO World Heritage Site.
