The Donguz Formation, Donguz Svita, or Donguz Rocks (Russian: Донгузские скалы) is a Middle Triassic geological formation that crops out on the right bank of Donguz River in Orenburg Oblast, Russia, across the settlement of Pervomaisky. The formation is equivalent to a biostratigraphic unit, the Donguz Gorizont. It is famous for its rich collection of the fossils of Middle Triassic tetrapods.[2][1][3]

It is a nature monument (особо охраняемых природных территорий (ООПТ)).[4]
