The Caistor Canal was a 4-mile (6.4 km) canal in Lincolnshire, England, constructed between 1793 and 1798. It fell into disuse sometime after 1850 and was legally abandoned in 1936. It ran from the River Ancholme, near South Kelsey toward Caistor through six locks, terminating at Moortown, 3.5 miles (5.6 km) away from its intended terminus at Caistor. Parts of it were dredged in 2010, to aid flood defences in South Kelsey.
