The Saco River is a river in northeastern New Hampshire and southwestern Maine in the United States. It drains a rural area of 1,703 square miles (4,410 km2) of forests and farmlands west and southwest of Portland, emptying into the Atlantic Ocean at Saco Bay, 136 miles (219 km) from its source. It supplies drinking water to roughly 250,000 people in thirty-five towns; and historically provided transportation and water power encouraging development of the cities of Biddeford and Saco and the towns of Fryeburg and Hiram. The name "Saco" comes from the Eastern Abenaki word [sɑkohki], meaning "land where the river comes out". The Jesuit Relations, ethnographic documents from the 17th century, refer to the river as Chouacoet.
