Julia I. Sand (1850–1933) was an American woman who corresponded with the American President Chester A. Arthur, beginning in late August 1881. Arthur saved twenty-three letters, all of which were discovered in 1958 after his grandson, Chester Alan Arthur III (also known as Gavin Arthur), sold his grandfather's papers to the Library of Congress. The last surviving letter is dated September 15, 1883. It is not known whether Arthur ever wrote back as no letter from him has ever been found. Sand often referred to herself as the President's "little dwarf", an allusion to the idea that in a royal court, only the dwarf would have the courage to tell the truth.
