David Pattee (July 30, 1778 – February 5, 1851) was a businessman, judge and political figure in Upper Canada.
In 1803, he left New Hampshire for the lower Ottawa River in Upper Canada because he was in debt and accused of forgery.
He set up a farm and formed a partnership with Thomas Mears to operate a water-powered sawmill near the Long Sault Rapids on the river.
In 1820, he ran against William Hamilton for a seat in the Legislative Assembly of Upper Canada for Prescott.
The Hamiltons had uncovered the original accusations of forgery against Pattee and attempted to unseat him on that basis.
