Abraham Clark (February 15, 1726 – September 15, 1794) was an American Founding Father, politician, slave owner, and Revolutionary War figure. He was a delegate for New Jersey to the Continental Congress where he signed the Declaration of Independence and later served in the United States House of Representatives in both the Second and Third United States Congress, from March 4, 1791, until his death in 1794.
Clark was born in Elizabethtown in the Province of New Jersey. His father, Thomas Clark, realized that he had a natural grasp for math so he hired a tutor to teach Abraham surveying. While working as a surveyor, he taught himself law and went into practice. He became quite popular and became known as "the poor man's councilor" as he offered to defend poor men who could not afford a lawyer. Clark entered politics as a clerk of the Provincial Assembly. Later he became high sheriff of Essex County and in 1775 was elected to the Provincial Congress. He was a member of the Committee of Public Safety.
Early in 1776, the New Jersey delegation to the Continental Congress was opposed to independence from Great Britain. As the issue heated up, the state convention replaced all their delegates with those favoring the separation. Because Clark was highly vocal on his opinion that the colonies should have their independence, on June 21, 1776, they appointed him, along with John Hart, Francis Hopkinson, Richard Stockton, and John Witherspoon as new delegates. They arrived in Philadelphia on June 28, 1776, and voted for the Declaration of Independence in early July. Clark remained in the Continental Congress through 1778, when he was elected as Essex County's Member of the New Jersey Legislative Council. New Jersey returned him twice more, from 1780 to 1783 and from 1786 to 1788. Clark, more than many of his contemporaries, was a proponent of democracy and the common man, supporting especially the societal roles of farmers and mechanics.
Clark retired before the state's Constitutional Convention in 1794 and died from sunstroke at his home in Rahway, New Jersey. He was buried at Rahway Cemetery.
