Río Grande (Spanish pronunciation: [ˈri.o ˈɣɾande]) is a municipality of Puerto Rico located in the Northern Coastal Valley, north of Las Piedras, Naguabo and Ceiba; east of Loíza and Canóvanas and west of Luquillo. Río Grande is spread over eight wards and Río Grande Pueblo (the downtown area and the administrative center of the city). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area.
Río Grande was founded on July 16, 1840, by Desiderio and Quilimaco Escobar, with the approbation of governor Miguel López. It was named after the Río Grande and is located where the Río Grande and the Río Espíritu Santo (Holy Spirit) join.

Local retail stores are aside the PR-3. Large shopping centers were not present mainly due to the closeness of the Canóvanas shopping district area. However, there is one large shopping mall located on 65fh of Infantry express way and 956ht street. Because it is relatively new many of its spaces are not leased yet. Together both cities are growing economically very fast and becoming the eastern pole of economy of the northeastern area of Puerto Rico attracting hotels, shopping malls, sport venues among others. Another thing that is making Río Grande more attractive to tourists and businesses alike is the newly constructed and opened Route 66 (or ruta 66), which makes it a lot more accessible and more appealing to home buyers.
