Prince Andrey Mikhailovich Kurbsky (Russian: Андрей Михайлович Курбский; Polish: Andriej Michajłowicz Kurbski; 1528–1583) was a Russian political figure, military leader, and political philosopher, known as an intimate friend and then a leading political opponent of the Russian tsar Ivan the Terrible (r. 1533–1584). His correspondence with the tsar provides a unique source for the history of 16th-century Russia.
