Slobodan Jovanović (Serbian Cyrillic: Слободан Јовановић) (December 3, 1869, Novi Sad, Austria-Hungary – December 12, 1958, London, United Kingdom) was one of Serbia's most prolific jurists, historians, sociologists, journalists and literary critics. He distinguished himself with a characteristically clear and sharp writing style later called the "Belgrade style". His contemporaries were Jovan Skerlić, Bogdan Popović, Pavle Popović and Branko Lazarević, all literary critics.
Liberal in his social and political views, he was perhaps Yugoslavia’s greatest authority on constitutional law; also a master of Serbian prose style, he was for nearly half a century a leader of the Serbian intelligentsia. He graduated law in Geneva in 1890. In 1905, he was a professor at the University of Belgrade's Law School until 1941. He was also a politician while in exile in London during World War II. He spent his later years in exile in London (1945–1958).
In Serbia, he is universally regarded as one of the most influential political thinkers of the turn of the century.
