The Magnetawan River is a river in Parry Sound District, Ontario, Canada, which flows 175 km from Magnetawan Lake inside Algonquin Provincial Park to empty into Georgian Bay at the community of Britt on Byng Inlet.
The River has numerous rapids, such as, "The Thirty Dollar Rapids", "The Fourteen", "The Ten", the "Potato Rapids", "Poverty Bay Chutes", and "Cody Rapids".
The town of Magnetawan is located on the river between Lake Cecebe and Ahmic Lake. Locks were built here on the river to allow steamboats to travel further down the river from the railway station at Burk's Falls. The locks officially opened on July 8, 1886 and are still in use today.
