'''Newhaven''' is a [[port town]] in the [[Lewes (district)|Lewes district]] of [[East Sussex]], England, lying at the mouth of the [[River Ouse, Sussex|River Ouse]].

The town developed during the [[Middle Ages]] as the nearby port of [[Seaford, East Sussex|Seaford]] began drying up, forcing a new port to be established. A sheltered harbour was built in the mid-16th century, and a [[breakwater (structure)|breakwater]] in the late 18th, to provide continued access to the sea. Newhaven increased in importance following the arrival of the railway in 1847, and regular cross-Channel ferry services to [[Dieppe]]. Though these have been reduced in the 21st century, Newhaven still provides regular ferry services and continues to be used as an important freight terminal. In 2021 the parish had a population of 12,854.
