Elizabeth "Eliza" Pinckney (née Lucas; December 28, 1722 – May 27, 1793)[1] was an American farmer.
Pinckney transformed agriculture in colonial South Carolina, where she developed indigo as one of its most important cash crops. Its cultivation and processing as dye produced one-third the total value of the colony's exports before the Revolutionary War. The manager of three plantations,[2] Pinckney had a major influence on the colonial economy.
Together with her husband Charles Pinckney, Eliza raised a daughter and two sons, Charles Cotesworth Pinckney and Thomas Pinckney, who became prominent politicians in South Carolina and were nominated for president and vice president of the United States by the Federalist Party.
