American Revolutionary War Edward Jessup (December 24, 1735 – February 3, 1816), together with his brother Ebenezer Jessup (July 1739 – 1818), was a large landowner in present-day New York State before the American Revolution, and later a soldier and political figure in Upper Canada, now the present-day Canadian province of Ontario, Canada.

In 1759, during the French and Indian War, Edward Jessup served as a Captain in the New York Militia under the leadership of British general Jeffery Amherst in the Lake Champlain region at the Battle of Ticonderoga.

Following the war, in 1764, he moved with his brother, Ebenezer, to Albany County, New York, where they established a community, known as Jessup's Landing, on the Hudson River.

In 1776, with other loyalists from this area, they joined Sir John Johnson's regiment, later forming their own corps, known as the King's Loyal Americans.

His son, Edward Jr., was elected to the 2nd Parliament of Upper Canada representing Grenville and became a lieutenant-colonel in the local militia.
