Carolina is a municipality located on the northeast coast of Puerto Rico. It lies immediately east of the capital San Juan and Trujillo Alto; north of Gurabo and Juncos; and west of Canóvanas and Loíza. Carolina is spread over 12 wards plus Villa Carolina (the downtown area and administrative center). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area, and home to Puerto Rico's main airport, the Luis Muñoz Marín International Airport.

The town was founded by Spanish colonists in 1816 as Trujillo Bajo ("lower Trujillo"), along with its counterpart Trujillo Alto after Trujillo, Spain. In 1857 it was renamed to San Fernando de la Carolina, later shortened to Carolina, after Charles II of Spain. The city is known as Tierra de Gigantes (Land of Giants), not only for well-known Carolina resident Don Felipe Birriel González (who was 7'11"), but also in honor of other people from Carolina, including poet Julia de Burgos and most notably the first Latin American player named to baseball's Hall of Fame, Roberto Clemente. Carolina was also home to Jesús T. Piñero, the first Puerto Rican to be appointed as governor by the United States government.

Carolina is one of Puerto Rico's most important tourist centers. Luis Muñoz Marín International Airport, while incorrectly thought to be in San Juan, it is actually located in Isla Verde, which is geographically part of Carolina. Also located in Carolina are a large group of hotels, which sit by Carolina's large beach area. The main Landmarks and places of interest are: Buena Vista Ruíns, Carolina Beach, Loíza's Big River, Isla Verde Club Gallístico, Luis Muñoz Marín International Airport, Jesús T. Piñero Monument, Julia de Burgos Park, Piñones Beach, Roberto Clemente Ciudad Deportiva.
