Georg Busolt (13 November 1850 – 2 September 1920) was a German historian of Classical history.

Busolt, born at Gut Kepurren (now in Chernyakhovsky District) near Insterburg, was the son of the East Prussian landowner Adolf Julius Busolt (1818–1900). He attended the Gymnasium at Insterburg and studied history and philosophy at the University of Königsberg. In 1874 he received for his dissertation Grundzüge der Erkenntnißtheorie und Metaphysik Spinozas ("The Foundation of Spinoza's Theory of Knowledge and Metaphysics"), for which he received his doctorate in the following year, the Kant Prize. Following a research tour of Italy and Greece, Busolt habilitated in 1878 at Königsberg with his work on Sparta.

His first chair received Busolt in 1879: He followed Christian August Volquardsen as Professor of Ancient History at the University of Kiel. Since this was Busolt's first post, at first he was an associate professor and became a full professor in 1881. After 18 years in Kiel Busolt changed for the winter semester 1897/98 at the University of Göttingen, where he again succeeded Volquardsen. In Göttingen, Busolt worked until his death in teaching and at research. The Prussian government appointed him to Privy Councillor in 1911. Busolt died at Göttingen in 1920.

Busolt dealt mainly with Greek history. To this end, he wrote a handbook on the ancient Greek city and his multi-volume Griechische Geschichte. Although he intended to cover the subject down to the Battle of Chaeroneia, Busolt's work goes only as far as the Peloponnesian War. Despite that his work has sometimes become outdated, it still occupies an important place in the secondary literature, especially for the time of the Peloponnesian War, due to his extremely extensive annotations, which covers all the primary sources then known and the secondary literature up to his time.
