Jan Prosper Witkiewicz

Jan Prosper Witkiewicz (Lithuanian: Jonas Prosperas Vitkevičius; Russian: Ян Вѝкторович Виткѐвич) (June 24, 1808–May 8, 1839) was a Polish-Lithuanian orientalist, explorer and diplomat serving the Russian Empire. He was a Russian agent in Kabul just before the First Anglo-Afghan War.

Surviving family accounts (supported by Polish literature) suggest that, most probably, he was a double agent who tried to provoke a major conflict between the British and Russian Empire in Central Asia to weaken the latter decisively and thus give his native country a chance to regain sovereignty. Though this is in juxtaposition to all other evidence, and also calls into question the reason for his dedication to success in his Missions. He was also the paternal uncle of Stanisław Witkiewicz.
