The Regional County Municipality of Portneuf was constituted as a regional administrative entity on November 25, 1981 by a Provincial decree creating the supralocal Regional County Municipality administration based on the (...) and therefore replacing the previously existing historic Portneuf County Corporation. While the new administrative boundary included most of the communities from its previous historic limits, a few municipalities were merged with bordering entities: St-Augustin-de-Desmaures, Sainte-Catherine-de-Portneuf, Notre-Dame-de-Montauban, Quebec. Those municipalities yet remained within the Electoral Federal Riding of Portneuf District (all but Notre-Dame-de-Mautauban).

The administrative county seat remained in Cap-Santé while moving from the County Corporation building to a newly built one located further east on 185, Route 138 at a slight distance from the historic village of Cap-Santé.


There are 21 subdivisions within the RCM:[2]
