The Whewell Professorship of International Law is a professorship in the University of Cambridge.
The Professorship was established in 1868 by the will of the 19th-century scientist and moral philosopher, William Whewell, with a view to devising "such measures as may tend to diminish the causes of war and finally to extinguish war between nations".
Holders of the Whewell chair have included three judges of the International Court of Justice.
