The Adur (//) is a river in Sussex, England; it gives its name to the Adur district of West Sussex. The river, which is 20 miles (32 km) long, was navigable for large vessels up as far as Steyning, where there was a large Saxon port, but by the 11th century the lower river became silted up and the port moved down to the deeper waters nearer the mouth in Shoreham-by-Sea.
The Adur begins as two separate branches, the western Adur and the eastern Adur, which meet 2km west of Henfield.
The western Adur rises at Slinfold from where it flows around Coolham and then through Shipley, where it meets Lancing Brook and flows on to West Grinstead and Knepp Castle. The western Adur is tidal as far north as Bines Bridge near Bines Green, south of West Grinstead.
The eastern Adur rises at Ditchling Common, in East Sussex, from where it crosses into West Sussex and meets another major stream at Twineham. At Shermanbury, the eastern Adur is fed by the Cowfold Stream. The Normal Tidal Limit is just below this at the footbridge near Shermanbury Church although a weir just above the confluence with the Western Adur means that only the highest tides reach here. Up to the early 1800s boats could navigate to Mock Bridge where the A281 crosses the Adur.
From west of Henfield, the two branches of the river meet, before flowing between Upper Beeding and Bramber, past Coombes, through a gap in the South Downs near Lancing College where the Adur is fed by the Ladywell Stream. The river continues on to the English Channel at Shoreham-by-Sea. The mouth of the Adur is now two miles (3 km) from the town centre of Shoreham due to longshore drift.
The Baybridge Canal uses part of the Adur's watercourse.
The name Adur is a relatively recent (probably 1612S) invention, based on the name of the Roman fort Portus Adurni which was mistakenly believed to be at Shoreham. The river had previously been known as the Bramber, and was also recorded as the Sore in the sixteenth century, the latter probably a back-formation by William Harrison's Description of England (1577) from Shoreham (often Sorham in early sources).
From Norman times the county of Sussex was divided into sections known as rapes. Each rape was typically centred on a river and river port and was guarded by a castle. Bramber rape was centred on the port of Bramber and the river Adur, with Bramber Castle located close to the river. At various times in the medieval period, Bramber, Steyning and New Shoreham were all major ports on the river. The western Adur also flows close to Knepp Castle, near Shipley.
