José Abad Santos, Filipino lawyer and jurist, 5th Chief Justice of the Supreme Court of the Philippines (d. 1942)
José Abad Santos y Basco (Spanish: [xoˈse aˈβað ˈsantos i ˈbasko], Tagalog: [hoˈse ʔaˈbad ˈsantos]: February 19, 1886 – May 2, 1942) was the fifth Chief Justice of the Supreme Court of the Philippines. He briefly served as the Acting President of the Commonwealth of the Philippines and Acting Commander-in-Chief of the Armed Forces of the Philippines during World War II, on behalf of President Quezon after the government went in exile to the United States. After about two months, he was executed by the Japanese forces for refusing to cooperate during their occupation of the country.

Together with Josefa Llanes-Escoda and Vicente Lim, he is memorialized on the Philippines' 1,000-Peso banknote depicting Filipinos who fought and died resisting the Japanese occupation of the Philippines during the Second World War.
