The Petite rivière Péribonka is a tributary waterway located in the Lac-Saint-Jean region of Quebec, Canada, offering a roughly 12-kilometre stretch of paddling in relatively protected waters. It flows into the broader Péribonka River system near Pointe-Taillon National Park, where the Péribonka River itself empties into Lac Saint-Jean.

Access to the Petite Péribonka is most conveniently made from the public boat launch in the town of Péribonka, reached by staying on Highway 169. The launch is situated at Rue Edouard Niquet, adjacent to the road, and is marked by docks. Parking is available nearby. From the launch, paddlers head out onto the Péribonka River and track along the shore until reaching the mouth of the Petite Péribonka. A local operator at the launch rents kayaks for day paddles and provides a small laminated map of the area. A public restroom is available in a small blue and white building at the dock.

The river itself features a sandy bottom, some cottage development, marshes, and stretches of wilderness. The protected nature of the waterway makes it a practical alternative when conditions on the open water of Lac Saint-Jean are unfavorable — particularly when wind or motorboat traffic makes a crossing toward Pointe-Taillon National Park less appealing. That crossing, visible to the left as paddlers head out from the launch, is an option worth considering if weather and water conditions permit.

The 12-kilometre length of the Petite Péribonka lends itself well to an out-and-back day paddle, making it accessible for paddlers looking for a manageable route without committing to open-lake conditions. The mix of marshland, sandy substrate, and undeveloped shoreline gives the river a varied character over its navigable length.
