Papineauville is a town and municipality in the Outaouais region of Quebec, Canada. It is the seat of the Papineau Regional County Municipality and part of Canada's National Capital Region. In 2001 its population was 2247.The municipality is bordered on the north side by the Petite-Nation River and on the south side by Pentecost Bay of the Ottawa River.HistoryThe Parish of Sainte-Angélique was formed in 1851, and the parish municipality with the same name was created in 1855. It was named after Angélique-Louise Cornud, wife of Denis-Benjamin Papineau, who donated land for the construction of the church and the rectory.Also in 1855, a post office was established with the name Papineauville. This may be named in honour of one of two persons named Papineau: Joseph Papineau (1752–1841), father of Louis-Joseph Papineau, who in 1801 bought the lordship of the Petite-Nation where the town formed; or Denis-Benjamin Papineau (1789–1854), brother of Louis-Joseph and husband of Angélique-Louise, and considered the founder of this place.In 1896, the Village Municipality of Papineauville separated from Sainte-Angélique. Its first mayor was Henri Bourassa.On November 29, 2000, the Village Municipality of Papineauville and the Parish Municipality of Sainte-Angélique were reunited and merged into the new Municipality of Papineauville. The name Sainte-Angélique now identifies the sector of Papineauville which corresponds to the territory of the former parish municipality.
