The Sand River (French: Rivière Sand[1]) is a river in the Unorganized North Part of Algoma District in Northeastern Ontario, Canada.

[4] The river is named after the sand bar formed across its mouth.

The river continues south into geographic Goodwillie Township,[10] flows over Lady Evelyn Falls, and takes in the left tributary Kwagama Creek.

It then heads southwest, descends a series of low cascades, passes under Ontario Highway 17 and reaches its mouth at Lake Superior.

There is a picnic area at the mouth of the river next to Highway 17 where many travelers stop to enjoy a view of the cascading falls,[4] and the Pinguisibi hiking trail follows the right bank from the river mouth.
