Nikolai Rysakov (Russian: Николай Иванович Рысаков; 1861–1881) was a Russian revolutionary and a member of Narodnaya Volya. He personally took part in the assassination of Tsar Alexander II, throwing a bomb that disabled the Tsar's carriage. A second bomb by an accomplice, Ignacy Hryniewiecki, was fatal to the Tsar. Rysakov was promptly arrested, put on trial, and hanged, along with other accomplices.
