Uckfield is a town in the Wealden district of East Sussex, in southern England. It is located on the southern edge of the Weald and on the River Uck, one of the tributaries of the River Ouse.The town was originally called Uccafield. Uccafield derives from the Celtic word for 'High' or 'Height' - Uchafedd, this in turn coming from the Indo European 'Uchch'ya'. When the Anglo Saxons heard this word they changed the 'fedd' part to something they understood - 'Feld' from which 'field' derives. The original river Uck name was most likely related to the ancient Celtic word for 'water' or 'stream' - Uisge, derivations uske, usci, that give river names still existing such as the Usk. When the Celts came along the sound of the river name was so close to the sound of Ucha that the name became Uch or Ucca over time and eventually Uck.
