The Madawaska River is a river in the Canadian province of Ontario .

The river has a length of 230 km and drains an area of ​​8470 km². It has its origins in Source Lake in the high elevations of Algonquin Provincial Park at an altitude of 450  m . From there it flows in an easterly direction and overcomes a difference in altitude of 380 m before it flows into the Ottawa River at Arnprior . In the late 19th century, the river was used to transport timber from the surrounding forest areas. In the early 1960s, the river was opened up for hydropower. Sections of the Madawaska River that are not dammed are used by canoeists , kayakers and amateur anglers.
