Simargl or Semargl (Old Church Slavonic: Семарьглъ, Симарьглъ) is a deity or mythical creature in East Slavic mythology, depicted as a winged lion or dog. The Zoryas, solar goddesses who are servants or daughters of the deity Dazhbog, keep Simargl chained to the star Polaris in the constellation Ursa Minor, to prevent him from breaking free and destroying the constellation, and causing the world to end.
An idol of Semargl was present in the pantheon of Great Prince Vladimir I of Kiev.
