The Philippines is a vast archipelagic country in the Pacific Ocean that consists of about 7,641 islands. Located in Southeast Asia, the country is known for its many diverse and spectacular natural features, including numerous lakes. Most lakes in the Philippines were created through volcanic and tectonic activity, which resulted in the formation of lake basins. Additionally, the obstruction of rivers due landslides and lava flows, for example, have also created many of the lakes in the Philippines. The country's largest lakes are highlighted below. Laguna de Baý is the largest lake in the Philippines.
