The Río Grande de Arecibo (also gazetted as Arecibo River in English) is a river of Puerto Rico. The Arecibo River is the fourth longest and second largest in discharge in Puerto Rico, after the Loíza River. Its headwaters lie in the mountains to the south of Adjuntas, from there it flows northward, passing along a gorge that is 200 m deep and 800–1,200 m wide, until it reaches the Atlantic Ocean near Arecibo Pueblo. The tributaries lie along the north side of the Cerro de Punta and the Utuado Pluton.
The tributaries to Río Grande de Arecibo basin include the Vacas, Pellejas, Garzas, Saltillo, Cidra, Grande de Jayuya, Caguana, Caonillas, Yunés, Limón, Jauca, Tanamá and Santiago rivers.
