Ivan Andreyevich Krylov (Russian: Ива́н Андре́евич Крыло́в) (February 13, 1769 – November 21, 1844) is Russia's best known fabulist. While many of his earlier fables were loosely based on Aesop and Jean de La Fontaine, later fables were original work, often satirizing the incompetent bureaucracy that was stifling social progress in his time.

Ivan Krylov was born in Moscow, but spent his early years in Orenburg and Tver. His father, a distinguished military officer, died in 1779, leaving the family destitute. A few years later Krylov and his mother moved to St.Petersburg in the hope of securing a government pension. There, Krylov obtained a position in the civil service, but gave it up after his mother's death in 1788. His literary career began in 1783, when he sold a comedy he had written to a publisher. He used the proceeds to obtain the works of Molière, Racine, and Boileau. It was probably under the influence of these writers that he produced Philomela, which gave him access to the dramatic circle of Knyazhnin.
