The New Cut is an artificial waterway which was constructed between 1804 and 1809 to divert the tidal river Avon through south and east Bristol, England. This was part of the process of constructing Bristol's Floating Harbour, under the supervision of engineer William Jessop. The cut runs from Totterdown Basin at the eastern end of St Phillip's Marsh, near Temple Meads, to the Underfall sluices at Rownham in Hotwells and rejoining the original course of the tidal Avon.
