The baselines of the Philippines () are the set of straight baselines encircling the Philippine archipelago from which the country's maritime entitlements are measured. The baselines were first established in 1961 through an act of Congress, and were later amended in April 2009 to conform with the United Nations Convention on the Law of the Sea (UNCLOS), to which the Philippines is a signatory. A total of 101 basepoints defining 100 baselines were identified under Republic Act No. 9522, which designated Mavulis Island as the northernmost point, Frances Reef as the southernmost, Pusan Point as the easternmost, and Mangsee Great (Coycoy) Reef as the westernmost point of the main Philippine archipelago.

Background The Philippines is an archipelago of 7,641 islands customarily enclosed by the lines demarcated by the Treaty of Paris in 1898 and its supplementary Treaty of Washington of 1900, and the Convention Between the United States and Great Britain in 1930, which came to be known in the Philippines as its International Treaty Limits. The government of the Philippines has maintained its position that the waters enclosed by the demarcation lines in the said treaties form part of its territorial waters regardless of its breadth and dimension.
