El Rao is a barrio located in Las Piedras, a municipality in the northeastern region of Puerto Rico situated between San Juan and the eastern coast. The barrio occupies approximately 22.89 square kilometers and forms part of Las Piedras' inland territory, positioned away from the municipality's coastal areas. Las Piedras itself is known for its mix of urban development and agricultural heritage, with El Rao representing the more rural and agricultural character that historically defined the municipality's interior.

The landscape of El Rao reflects the coastal lowland geography typical of northeastern Puerto Rico, with relatively flat to gently rolling terrain suited to mixed land uses. This area has traditionally supported agricultural activities alongside scattered residential development, creating a pattern of larger parcels interspersed with smaller family-owned properties.
