Rivière Sautauriski is a 35.1-kilometre tributary of the Jacques-Cartier River flowing entirely within Jacques-Cartier National Park in the Capitale-Nationale administrative region of Quebec, Canada. The river originates at Nouvel Lake and ultimately drains southward into the broader Jacques-Cartier River watershed before reaching the St. Lawrence River near Donnacona. The river traverses the Sautauriski sector of the park, passing through and connecting with Sautauriski Lake — the largest of the park's more than 216 bodies of water at approximately 229 hectares — before continuing its course through the boreal forest landscape. The valley is primarily served on its eastern side by Route 175, which links Quebec City and Saguenay, with secondary roads supporting forestry operations and recreational tourism. The surrounding region is characterized by classic boreal forest, and the entire watershed sits within a nationally protected area managed by the Société des établissements de plein air du Québec (Sépaq).
