Joseph Périnault (October 8, 1732 – January 31, 1814) was a fur trader, seigneur and political figure in Lower Canada.
In 1765, with Montreal merchant Pierre Foretier, he purchased a large part of the seigneury of Île-Bizard and the sub-fief of Closse, later selling his share to Foretier.
Périnault was named a justice of the peace for Montreal district in 1796.
In the same year, he was elected to the Legislative Assembly of Lower Canada for Huntingdon County; he was elected in Montreal West in 1800.
From 1806 until his death in 1814, Périnault lived with his son, Pierre-Joseph, who was a parish priest at Sault-au-Récollet in north Montreal; he was buried in the parish church.
