Abraham Markle (October 26, 1770 – March 6, 1826) was a businessman and political figure in Upper Canada and co-proprietor of Terre Haute, Indiana.
Four of his brothers served with Butler's Rangers during the American Revolution; they settled at Newark (Niagara-on-the-Lake) after the war and he joined them for a time, but he later moved back to New York state.
[further explanation needed] In 1813, with Joseph Willcocks, he opposed the suspension of habeas corpus in the province.
Markle accompanied the American Raid on Port Dover, in which the village was burned down.
He built and operated a mill[1] on Otter Creek north of that village and became involved in other businesses in the area.
