Pierre Bruneau (July 22, 1761 – April 13, 1820) was a merchant and political figure in Lower Canada.

He was born in the town of Quebec in 1761, the son of a merchant involved in the fur trade, and studied at the Petit Séminaire de Québec.

In 1786, he took over the family business after his father returned to Poitiers in France; Bruneau opened a second store in Chambly and expanded into the trade in grain, cloth and alcohol.

Like many members of the parti canadien, Bruneau was opposed to judges sitting in the legislative assembly.

His nephew François-Pierre Bruneau later served as a member of the legislative council for the Province of Canada.
