Edgar Stanton Maclay (18 April 1863 – 2 November 1919) was an American journalist and historian.
He then researched American history for over a year in England, France and Germany.
He edited the Journal of William Maclay and was the author of History of the United States Navy, which occasioned much controversy and brought about his dismissal from government employ, by order of President Roosevelt, in 1901.
The ground of this action, following Maclay's refusal of an official request for his resignation, was a passage in the History stigmatizing Rear Admiral Winfield Scott Schley as a “caitiff, poltroon and coward” for his conduct in the naval fight off Santiago, Cuba on 3 July 1898.
Maclay also wrote Reminiscences of the Old Navy and The History of American Privateers.
