Pinckney, Charles (1757–1824), a United States statesman and diplomat. Pinckney was a signer of the U.S. Constitution. A constitutional plan he submitted, known as the Pinckney Draught, has been lost, but it is believed to have had strong influence in shaping the document.

Pinckney was born in Charleston, South Carolina, a second cousin of Charles Cotes-worth Pinckney and Thomas Pinckney. He served in the state militia in the Revolutionary War and was a member of the Congress of the Confederation, 1784–87. Pinckney was governor of South Carolina, 1789–92, 1796–98, and 1806–08. By 1798 he had switched his allegiance from the Federalists to Jefferson's Republican party, forerunner of the Democratic party. Pinckney was minister to Spain, 1801–05. He served in the U.S. Senate, 1798–1801, and the House of Representatives, 1819–21.
