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 of forests and farmlands west and southwest of Portland, emptying into the Atlantic Ocean 134 miles from its origin at Saco Bay.

It rises at Saco Lake in Crawford Notch in the White Mountains and flows generally SSE through Bartlett and Conway in Carroll County, New Hampshire before crossing into York County, Maine. After running through six hydropower stations, it crosses under Interstate 95 and passes between Saco and Biddeford, where it is bridged by U.S. Route 1. It enters Saco Bay on the Atlantic with Camp Ellis in Saco on the north shore and Hills Beach in Biddeford on the south shore.

The United States government maintains two river flow gages on the Saco river. The first is at Conway, New Hampshire ([43°59′27″N, 71°05′29″W]) where the rivershed is 385 square miles. Flow here has ranged from 47,200 to 40 cubic feet per second. The second is at Cornish, Maine ([43°48′29″N, 70°46′53″W]) where the rivershed is 1,293 square miles. Flow here has ranged from 46,600 to 244 cubic feet per second.
