Seend Locks (grid reference ST933613) are at Seend Cleeve, Wiltshire on the Kennet and Avon Canal, England.
The five locks were built between 1718 and 1723 under the supervision of the engineer John Hore of Newbury. They have a rise/fall of 38 ft 4ins (11.68m).
During the 19th century there were several wharves at Seend primarily serving the Seend Iron Works but these have been disused for many years. The five locks at Seend Cleeve are numbered 17 to 21. The Barge Inn is next to Seend Wharf bridge and between locks 18 and 19.
A back pump has been installed to ensure that there is water to fill the locks, the outflow of which is on a road bridge above the top lock.
