The Rivière Port-Daniel du Milieu flows in the administrative region of Gaspésie–Îles-de-la-Madeleine, Quebec, Canada. More specifically, this river crosses successively:
The "Rivière Port-Daniel du Milieu" is a tributary of the north shore of the barachois of the hamlet of "Rivière-Port-Daniel" which opens to the south in the bay of Port-Daniel, located on the North shore of Chaleur Bay; the latter in turn opens eastward onto the Gulf of St. Lawrence.
The "Port-Daniel du Milieu river" takes its source from mountain streams in the southwest part of the township of Weir which is part of the unorganized territory of Rivière-Bonaventure.

These two strips of land are linked by the Canadian National railway bridge and by route 132.
This barachois empties on the south-east side into the "Baie de Port-Daniel du Milieu", which opens towards the south-east into Chaleur Bay. This bay, the width of which at the opening is, is delimited by the "Cap de la Vieille" (on the east side) and by the Pointe du Sud-Ouest.
