Edwin de Leon (May 4, 1818 – November 30, 1891) was a Confederate diplomat, writer, and journalist.
De Leon was born in Columbia, South Carolina of parents Mordecai Hendricks De Leon and Rebecca Lopez. He was the brother of newspaperman Thomas Cooper de Leon as well as another brother David Camden De Leon and three sisters, Agnes, Maria Louisa, and Adeline Mary (who married Joseph Henry Adams, of Boston). Edwin's father Mordecai De Leon, a physician, removed from Philadelphia to Columbia, South Carolina, and was mayor of that city for several years. De Leon married Ellen Mary Novlan of Rothgar, Ireland, on August 25, 1858, in Somerset, England.
(In a biography of Jefferson Davis Edwin De Leon is incorrectly identified as "Daniel De Leon". Daniel De Leon was an American socialist organizer and theoretician and the long-time leader of the Socialist Labor Party. When the Civil War began Daniel De Leon was eight years old and living on the island of Curaçao.)[Eaton, Clement: Jefferson DavisThe Free Press, A Division of Macmillan Publishing Co., Inc.

De Leon graduated from South Carolina College, where he was a member of the Euphradian Society, and studied law, but soon turned to literature and politics. He became an active collaborator on the Southern Review, the Magnolia, the Southern Literary Messenger, and other periodicals. Removing to Savannah, Georgia, he took editorial charge of the Savannah Republican and made it a political factor in the state; his next charge was the Columbia, South Carolina Telegraph, a daily.
De Leon was a leader of the Young America movement. At the invitation of a committee of Southern members of Congress, De Leon established, in Washington The Southern Press, which had a large circulation during the early fifties. For his services during the Pierce campaign, Pierce appointed him consul-general to Egypt, which position he filled for two terms with marked success. At the commencement of the Crimean War, an order was issued by the Porte expelling all Greeks from the Ottoman dominion. The Greeks in Egypt appealed to De Leon, who took them under the protection of the American flag, guaranteed their good behavior, and insisted that they should not be interfered with. The home government approved his course, and Congress paid him the compliment of ordering the printing of his dispatches. The King of Greece tendered him the grand cross of the Order of San Sauveur, but Leon declined on the ground that it was anti-republican.
