Quezon, officially the Province of Quezon, is a province in the Philippines located in the Calabarzon region on Luzon. Kalilayan was the first known name of the province upon its creation in 1591. Around the middle of the 18th century, it was changed to Tayabas. In recognition of the second president of the Philippines, Manuel L. Quezon, the name of Tayabas Province is changed to Quezon. Lucena, the provincial capital, the seat of the provincial government, and the most populous city of the province, is governed independently from the province as a highly urbanized city. To distinguish the province from Quezon City, it is sometimes called Quezon Province, a variation of the province's official name.
