Nerchinsk katorga (Russian: Нерчинская каторга, Nerchinskaya katorga) was a katorga system of the Russian Empire in the Nerchinsk okrug of Transbaikalia (today's Chita Oblast), between rivers Shilka and Argun, near the border to Mongolia, in the 18th to 20th centuries.
In 1886, after a failed attempt to free fellow-conspirators Piotr Bardowski (1846-1886) and Stanisław Kunicki (1861-1886) from the Warsaw Citadel who had been sentenced to death, he was arrested by Tsarist police and, in 1887, sent to penal servitude at Tunka.
