The Vyatka or Viatka (Russian: Вятская лошадь, vyatskaya loshad) is an endangered breed of horse native to the former Vyatka region, now the Kirov Oblast of the Russian Federation.

[4]: 512 The Vyatka was influenced by the climate and terrain of the Kirov, Udmurtia and western Perm regions; Estonian horses and Kleppers brought to northern Russia in the fourteenth century by Novgorod colonists may have affected its conformation, as may later imports of Estonian horses for mining work in the Ural Mountains.

By the middle of the nineteenth century it was considered the best horse for pulling troikas; some were exported from the Vyatka region, including to Poland.

[1]: 339 In 1917 the breed was virtually extinct; some efforts at re-establishment were made after the Russian Revolution.
