Alexander Nikolayevich Radishchev (August 31 [O.S. August 20] 1749 – September 24 [O.S. September 12] 1802) is a Russian author and social critic who is arrested and exiled under Catherine the Great.

He brings the tradition of radicalism in Russian literature to prominence with the publication in 1790 of his Journey from St. Petersburg to Moscow.

His depiction of socio-economic conditions in Russia earns him exile to Siberia until 1797.
