History
The seigneury of Portneuf was granted in 1647 by the Company of the Hundred Associates to Jacques Leneuf de La Poterie.
He was the alternate governor of Trois-Rivières from 1645 to 1662 and interim governor of New France.
The name was also sometimes spelled port neuf, apparently has a descriptive origin inspired by the fact that a new port was under construction in 1636 at the mouth of the river.
