The Andover Canal was a canal built in Hampshire, England. It ran 22 miles (35 km) from Andover to Redbridge through Stockbridge and Romsey. The canal had a fall of 179 feet (55 m) through 24 locks, and for much of its length paralleled the River Anton and River Test. It opened in 1794, but was never a commercial success. The only dividend paid to shareholders was in 1859, using the proceeds from the sale of the canal to the London and South Western Railway, who bought it to lay a railway line along much of its course. The railway line is now also defunct.
The first survey for an Andover Canal was carried out in 1770 by Robert Whitworth
