A water horse (also compounded as: waterhorse) is a mythical creature that appears in multiple forms in Celtic and Nordic folklore. Celtic incarnations includes: the Welsh Ceffyl Dŵr, Irish Capaill Uisce, the Scottish each-uisge and kelpie. In Nordic folklore, the water horse is a shape taken on by the nixie, in Swedish called bäckahästen ("the brook horse"), in Faroese nykur ("nixie").
