Luquillo (Spanish pronunciation: [luˈkiʎo]) is a town and municipality of Puerto Rico located in the northeast coast, northwest of Fajardo; and east of Rio Grande.

It lends its name to the Sierra de Luquillo, where El Yunque National Forest is located.

It is nestled between the blue waters of the Atlantic and the El Yunque National Forest, a rainforest, giving it a diverse and unique ecology.

During certain times of the year, it is not unusual to encounter rare or endangered species of fauna (like the leatherback turtle) while visiting in Luquillo.

In Luquillo, rivers were breached, there were landslides, the electrical power collapsed, and 1100 homes were destroyed or damaged.

The municipal buildings, central square and large Catholic church are located in a barrio referred to as "el pueblo".

This huge plantation of majestic coconut palms shades more than a mile of fine and shimmering sand.

It offers cafeterias, public bathrooms with showers, access for disabled people, and an ample parking lot.

The Fiestas Patronales de San Jose is a religious and cultural celebration that generally features parades, games, artisans, amusement rides, regional food, and live entertainment.

In the center stripe resides the coat of arms of the municipality superimposed and surrounded by two palm tree leaves crossed at the bottom.
