The City of Naga is located in the Bicol Region, a peninsula on the southeasternmost tip of the island of Luzon.

With a relatively small land area compared to all cities in Bicol which accounts for it being the most densely-populated city in the region, Naga City is locally known as the "Heart of Bicol". It is the religious and cultural center of the Bicol region. Residents of the City are called Nagueños.

Situated at the center of the Bikol peninsula and surrounded on all sides by rich agricultural, forest and fishing areas, Naga is also at the confluence of the Naga and Bikol Rivers. Thus, it has always been an ideal place for trade, and as center for schools and church and government offices.
