William Leete Stone Jr. (4 April 1835 – 11 June 1908) was an American historical writer and journalist.
The son entered Brown University, but left college in 1856 and spent several months in Germany in acquiring a knowledge of the German language with a view of translating into English several military works bearing upon the history of the American Revolution.
He practised law at Saratoga Springs during 1860–63, and in 1864-67 was city editor of the New York Journal of Commerce.
At the laying of the cornerstone of the monument on 17 October 1877, the centennial of Burgoyne's surrender, he delivered the historical address.
Stone died in Mount Vernon, New York.
