Gertrud Bing (7 June 1892 – 3 July 1964) was a German art historian and director of the Warburg Institute.
Her doctoral dissertation, written under the supervision of Ernst Cassirer, concerned Lessing and Leibniz.
In December 1933, the library was moved to London when the Nazis rose to power, becoming the Warburg Institute.
With her partner, Fritz Saxl, the new institute's first director, she settled in Dulwich.
After the death of Frankfort in 1954, Bing in 1955 became director of the institute and Professor of the History of the Classical Tradition.
