Gustave Edmund von Grunebaum (1 September 1909 in Vienna Austria – 27 February 1972 in Los Angeles United States, born Gustav Edmund Ritter von Grünebaum) was an Austrian historian and Arabist.
Born in Vienna, Grunebaum received his Ph.D. in Oriental Studies at the University of Vienna in 1931 with a dissertation on classical Arabic poetry. When Nazi Germany absorbed Austria in the Anschluss of 1938, he went to the United States, where he was given a position at the Asia Institute in New York City by Arthur Upham Pope, an eminent authority on Persian art and antiquities who used the institute to help a number of displaced German scholars find work in the United States in the 30's and 40's. In 1943, he moved on to the University of Chicago, and was made professor of Arabic in 1949. In 1957, Grunebaum was appointed professor of Near Eastern History and the director of a new department called the Near Eastern Center at UCLA. He died in Los Angeles at the age of 62 following brief battle with cancer. The Near Eastern Center was later renamed in Grunebaum's honor.
Grunebaum was married to Giselle Steuerman.
