Río Canelo is a natural watercourse in the Región de Magallanes y de la Antártica Chilena that flows generally northward before emptying into Seno Otway, an inlet connected to the broader Pacific Ocean system between the Península de Brunswick and Isla Riesco, roughly 65 km northwest of Punta Arenas.

The river sits within its own designated watershed — item 125 in Chile's national basin inventory — and is surrounded by mountains and native forest.

The area features open grassy flats and is considered a public access point, though reaching the more remote stretches requires a high-clearance or 4x4 vehicle. The setting draws visitors looking to fish, camp, and experience the rugged Patagonian backcountry.
