The Rivière Pikauba is a northward-flowing river approximately 91 km (57 mi) long, located in the Saguenay–Lac-Saint-Jean administrative region of Quebec, Canada. It originates within the Laurentides Wildlife Reserve and flows to Lake Kénogami, serving as a major tributary of that lake. The river drains approximately 495 km² of the larger 3,390 km² Lake Kénogami watershed.

Canot Kayak Québec has produced a three-map bundle covering the entire paddling route of the river, available through the Avenza Maps app (iOS and Android) at no cost. These maps indicate put-in and take-out points, rapids, portages, camping sites, and other points of interest along the river corridor. One documented paddling route covers the last approximately 20 km of the river, from above Pointe aux Écorces down to Lac Kénogami. Another route description references a starting point near Lac Davenport, potentially beginning on the Rivière Chicoutimi before transitioning to the Pikauba.

Access to the river is facilitated by Quebec Route 175, which connects Quebec City to Saguenay and passes near the Laurentides Wildlife Reserve, and Route 169, which provides entry points toward Hébertville and Lac Saint-Jean. Secondary forest roads branch off these main routes for more remote access. The proximity of Lac-Pikauba supports camping at reserve sites equipped with basic facilities.

The river flows through the Laurentides Wildlife Reserve, a protected wilderness area, and the surrounding terrain is heavily forested. The upper reaches are noted for clear water and brook trout fishing, subject to provincial regulations that permit catches from April to September in designated sections. The river corridor includes visible rapids, which are highlighted along the hiking trail that follows the riverbanks near Mont-Apica. Summer is identified as a season for paddling activity on the river. The area is managed with an ecotourism focus within the reserve, and visitors should be aware of applicable provincial regulations when planning a trip.
