Arthur Jerome Eddy (November 5, 1859 - July 21, 1920 in New York City, New York) was an American lawyer, author, art collector, and a prominent member of the first generation of American Modern art collectors. His book Cubists and Post-Impressionism was the first American book promoting these new art movements and the work of Wassily Kandinsky. Eddy's collection was distinguished by the inclusion of German expressionists and Wassily Kandinsky.
