Avoncliff Aqueduct (gbmapping|ST803599) carries the Kennet and Avon Canal over the River Avon and the Bath to Westbury railway line, at Avoncliff in Wiltshire, England.

It was built by John Rennie and chief engineer John Thomas, between 1797 and 1801.

The aqueduct consists of three arches and is 110 yards long with a central elliptical arch of 60 ft (18.3 m) span with two side arches each semicircular and 34 ft (10.4 m) across, all with V-jointed arch stones. The spandrel and wing walls are built in alternate courses of ashlar masonry, and rock-faced blocks.
