Halsey Cooley Ives (27 October 1847 – 5 May 1911) was the founder of the Saint Louis School and Museum of Fine Arts.
The institution later became two distinct bodies; the Saint Louis Art Museum, and the Washington University School of Art which includes the Mildred Lane Kemper Art Museum.
Ives was also a landscape painter, but is best remembered for the organization, administration, and popularization of art in Saint Louis, Missouri.
