The North Yamaska river (in French: Rivière Yamaska Nord) is a tributary of the Yamaska river. It flows over 47.8 kilometres (29.7 mi) on the south shore of the Saint Lawrence river in Quebec, Canada and passes through five municipalities, some of them sourcing their fresh water from it.
Like the rest of the Yamaska, it is an important source of life, though urban development, agriculture and industrial uses have had a negative impact on the ecosystem depending on its waters since the colonization of the Eastern Townships.
An awakening in regards to pollution in the North Yamaska has led to an increasing amount of movements such as collective art and eco-friendly action around the river; efforts are noted in local municipalities and their regional county municipalities to alter the impacts of towns and villages on water quality.
