Maly Yeravna (Russian: Малое Еравное; Russian Buryat: Бага Ярууна) is a fresh water body in the Yeravninsky District, Buryatia, Russia. There are two inhabited places by the lake, Tuldun in the northwestern shore and Shiringa in the northeastern. The Yeravninsky penitentiary settlement was established by Russian Cossack explorers on the eastern bank of the lake in 1675. But by the beginning of the 18th century the prison had lost relevance and only 11 houses and the former prison clerk hut remained.
