Roger Sherman (April 19, 1721 – July 23, 1793) was an early American statesman, lawyer, and a Founding Father of the United States. He is the only person to sign all four great state papers of the United States: the Continental Association, the Declaration of Independence, the Articles of Confederation, and the Constitution. He also signed the 1774 Petition to the King.

Born in Trenton, New Jersey, Sherman established a legal career in Litchfield County, Connecticut, despite a lack of formal education. After a period in the Connecticut House of Representatives, he served as a justice of the Superior Court of Connecticut from 1766 to 1789. He represented Connecticut at the Continental Congress, and he was a member of the Committee of Five that drafted the Declaration of Independence.

Sherman served as a delegate to the 1787 Philadelphia Convention, which produced the United States Constitution. After Benjamin Franklin, he was the second oldest delegate present at the convention. He favored granting the federal government power to raise revenue and regulate commerce, but initially opposed efforts to supplant the Articles of Confederation with a new constitution. He ultimately came to support the establishment of a new constitution and proposed the Connecticut Compromise, which won the approval of both the larger states and the smaller states.After the ratification of the Constitution, Sherman represented Connecticut in the United States House of Representatives from 1789 to 1791. He served in the United States Senate from 1791 to his death in 1793.
