Peter Patterson (May 11, 1768 – June 12, 1851) was an English-born businessman and seigneur in Quebec.
He came to Quebec in 1801 and was employed by Henry Usborne in a timber and ship building business.
In 1811, he acquired property at Montmorency Falls where he established a large sawmill operation.
In 1846, he helped found the Quebec and Lake Superior Mining Association and served as its first president.
His daughter Mary Jane married George Benson Hall, who took over the operation at Montmorency after Patterson's death.
