Portneuf County, Quebec

Portneuf County is an historic county in Quebec, Canada west of Quebec City on the Saint Lawrence River. The county seat was Cap-Santé. It was bounded on the west by Champlain County on the northeast by Quebec County, and on the south by Lotbiniere County. In the early 1990s Quebec abolished its counties and most of Portneuf County became the Portneuf Regional County Municipality. The southeastern part of the county was transferred to La Jacques-Cartier Regional County Municipality and the Quebec Urban Community (now Quebec City) while parts of western Portneuf County was transferred to Mékinac Regional County Municipality.
