Quezon, officially the Province of Quezon and historically known as Tayabas, is a province in the Philippines located in the Calabarzon region on Luzon. Lucena, a highly urbanized city governed separately from the province, serves as the provincial capital and its most populous city. The name of the province came from Manuel L. Quezon, the president of the Philippines from 1935 to 1944. The province was known as Kalilayan upon its creation in 1591, renamed as Tayabas by the 18th century, before settling on its current name in 1946. To distinguish the province from Quezon City, it is also known as Quezon Province, a variation of the province's official name.
