Stanton Loomis Catlin (February 19, 1915 – November 26, 1997) was an American art historian, specializing in Latin America. After studying at Oberlin College and the Academy of Fine Arts, Prague, he was to have studied European modern art. The Second World War interrupted these plans and he instead focused on Latin American art. During the war Catlin assisted with exhibiting American art in Latin America, served as a Latin American specialist with the Office of the Coordinator of Inter-American Affairs and as a lecturer at the University of Chile. At the war's end he served with the United Nations Relief and Rehabilitation Administration in Germany, assisting displaced persons.
After the war Catlin became executive director of the American Institute of Graphic Arts, then curator at the Minneapolis Institute of Art. Whilst director of the Yale University Art Gallery he won a Grammy award for best album notes in 1965 for an essay on Mexican art and also curated the first US exhibition entirely of Latin American art. Catlin was afterwards appointed by the Center for Inter-American Relations (now the Americas Society) as director of their art gallery before joining the staff of Syracuse University in 1974. He became professor emeritus in 1986. From 1994 to 1997 he compiled a list of 150 Mexican mural paintings in the United States for the National Autonomous University of Mexico.
