The Central Bank of the Philippines introduced the one thousand peso denomination in December 1991. The note features the portraits of former Chief Justice José Abad Santos; Josefa Llanes Escoda, civic worker and one of the founders of the Girl Scouts of the Philippines; and Vicente Lim, a general in the Philippine Army who was the first Filipino graduate of West Point. The three are considered heroes of the resistance against the Japanese occupation of the Philippines. The obverse also features the eternal flame and laurel leaves.

The note is predominantly blue in color. The reverse features the Banaue Rice Terraces, Manunggul Jar cover and Langgal, representing the three islands of the Philippines (Luzon, Visayas, and Mindanao, respectively).
