Aurora Antonia Aragon Quezon (born Aurora Antonia Aragón 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.
Five years after her husband's death, she and her daughter María Aurora ("Baby") were assassinated while they were en route to Baler to open a hospital dedicated to President Quezon. The province of Aurora was named in her memory.
