The Wey and Arun Canal is a partially restored, 23-mile-long (37 km) canal in the south east of England. It runs southwards from the River Wey at Shalford, Surrey to the River Arun at Pallingham, in West Sussex. The canal comprises parts of two separate undertakings – the northern part of the Arun Navigation, opened in 1787 between Pallingham and Newbridge Wharf, and the Wey and Arun Junction Canal, opened in 1816, which connected the Arun at Newbridge to the Godalming Navigation near Shalford, south of Guildford. The canal was built with 26 locks.

Passing through a rural landscape, there was little freight traffic to justify its continued existence, and the canal was officially abandoned in 1871.

Without maintenance, the canal gradually became derelict over much of its length. However, since 1970, active restoration by The Wey & Arun Canal Trust has resulted in several miles of the waterway being restored to navigable standard. Work is continuing, with the ultimate aim of re-opening the entire canal to navigation.

The River Arun was used in an unimproved condition for centuries, but work was carried out on the river itself and the port of Arundel in the 16th century, which allowed boats to reach Pallingham Quay near Pulborough by 1575. An Act of Parliament received the Royal Assent on 13 May 1785, entitled "An Act for amending and improving the Navigation of the River Arun, from Houghton Bridge, in the parish of Houghton, in the county of Sussex, to Pallenham Wharf, in the parish of Wisborough Green, in the said county; and for continuing and extending the Navigation of the said River Arun, from the said Wharf, called Pallenhara Wharf, to a certain Bridge, called New Bridge, situate in the parishes of Pulborough and Wisborough Green, in the said county of Sussex".

As its name describes, this Act authorised works to improve the Arun upstream from Houghton Bridge (the tidal limit) to Newbridge, near Billingshurst. The route involved a new artificial cut of 4.5 miles (7.2 km) from Newbridge along the river to Pallingham, crossing the river by an aqueduct on three strong brick arches at Lordings Lock near Wisborough Green. An undershot waterwheel of a design unique on the waterway system was built into the aqueduct. Driven by the flow of the river this had scoops on the back of the blades which raised a small proportion of the flowing water into the higher canal. This was completed in 1787. A second artificial cut was added in 1790 from Coldwaltham to Stopham, including a 375-yard (343 m) tunnel under Hardham Hill, which avoided a large bend in the river near Pulborough, saving 5 miles (8.0 km).
