Capt. John Alden Jr. (ca. 1626 or 1627 – March 25, 1702 [O.S. March 14, 1701]) was a 17th-century American soldier, politician, merchant, and sailor. He was a well-known public figure in his time but is now chiefly remembered as a survivor of the Salem witch trials, of which he wrote a much quoted and studied account.
