Georgy Porfiryevich Sudeykin (Russian: Георгий Порфирьевич Судейкин; 11 April 1850 – 16 December 1883 Saint Petersburg) was a Russian Gendarme colonel, the inspector of the Saint Petersburg Department for Protection of Communal Security and Order.

On 11 February, he and two officers raided a house where six of the buntari, five men and a woman named Natalya Armfeldt were hiding.

[1] Sudeykin had managed to recruit one of the Narodnaya Volya leaders, Sergey Degayev, as his agent.

Degayev's information led to arrest of Narodnaya Volya's leader Vera Figner and many other important members of the organization.

[5][6] Degayev, with the help of Narodnaya Volya, managed to escape from Russia to the United States, where he lived under the name of Alexander Pell.
