The Russian tortoise (Agrionemys horsfieldii), also commonly known as Horsfield's tortoise or the Central Asian tortoise, is a threatened species of tortoise. Both the specific name, horsfieldii, and the common name "Horsfield's tortoise" are in honor of the American naturalist Thomas Horsfield. This species is traditionally placed in Testudo. Due to distinctly different morphological characteristics, the monotypic genus Agrionemys was proposed for it in 1966.
