Aurora Antonia Quezon (née de Aragon y Molina; February 19, 1888 – April 28, 1949) was the wife of Philippine President Manuel Luis Quezon and the First Lady of the Philippines from 1935 to 1944. Although she is recognized as the second First Lady of the Philippines, she was actually the first spouse of a Philippine president to be addressed as such, the honorific being unknown in the Philippines prior to Manuel Quezon's presidency. Much beloved by Filipinos, Quezon was known for involvement with humanitarian activities and served as the first Chairperson of the Philippine National Red Cross.
