Julius Stone (7 July 1907 – 1985) was Challis Professor of Jurisprudence and International Law at the University of Sydney from 1942 to 1972, and thereafter a visiting Professor of Law at the University of New South Wales and concurrently Distinguished Professor of Jurisprudence and International Law at the Hastings College of Law, University of California.

He is the author of 27 books on jurisprudence and international law, and is hailed by his official biography at the Julius Stone Institute of Jurisprudence as one of the premier legal theorists.

Stone was born in Leeds, England to parents who were poor Lithuanian Jewish refugees.

Stone received a scholarship to Oxford University, where he earned Bachelor of Arts (Jurisprudence), Bachelor of Civil Law and Doctor of Civil Law degrees. He followed this with a Master of Laws from Leeds University, and then a Doctor of Juridical Science from Harvard University.

Stone taught at Harvard, and briefly at Leeds, then went to New Zealand where he worked at Auckland University College. In 1942, he was appointed Challis Professor of Jurisprudence and International Law at the University of Sydney, a position he held until 1972. Stone's appointment was controversial for several reasons; he was perceived to have a radical jurisprudential stance, some wanted the Chair to be held open until the end of the war as it was suggested that there were suitable candidates in active service. It was suspected that the fact that he was a Jew also played a role. A debate over his appointment was carried out in both the Australian parliament and local newspapers; the Chancellor of the University, and two Fellows of the University Senate, resigned in protest. This early experience of anti-Semitism influenced his lifelong commitment to justice, according to his biographer, Leonie Star (Star 1993).
