Viscount Kōno Togama (河野敏鎌, 29 November 1844 – 20 April 1895) was a Japanese statesman in Meiji period Japan.

In 1862, along with 59 other Tosa samurai, he marched on Kyoto and Edo in an attempt to influence national policy, but was captured by security forces of the Tokugawa shogunate in 1863 and sentenced to six years in prison.

After the Meiji Restoration, Kōno was freed and was recruited by fellow Tosa countryman Gotō Shōjirō to assist Etō Shimpei in the administration of Osaka.

However, with increasing ex-samurai discontent erupted into open rebellion in various locations, he was assigned to assist Ōkubo Toshimichi in restoration of central government authority in Kyūshū.

He treated Etō very roughly during his trial, refusing him a chance to defend his actions in court, and pushing for an early death verdict.
