The Piedras River is a coastal river in southwestern Spain, whose course is located entirely in the province of Huelva. It rises in the municipality of El Almendro, although most of the streams that give rise to it and that come from the Sierra del Almendro, are born in the municipality of Villanueva de los Castillejos. It runs from north to south and flows between the Flecha de Nueva Umbría (Lepe) and Nuevo Portil (Cartaya).
