The Zaporozhian Cossacks, Zaporozhian Cossacks Army, Zaporozhian Army () or simply Zaporozhians (, , ) were Ukrainian Cossacks who lived beyond the rapids of the Dnieper River, the land also known as the Wild Fields in Central Ukraine. Today most of its territory is flooded by the waters of Kakhovka Reservoir. The name Zaporozhtsi comes from the location of their fortress, the Sich, in Zaporozhzhia, the ‘land beyond the rapids’ (from za ‘beyond’ and poróhy ‘river rapids’).
