The Sleaford Navigation is a 12.5 mile canalisation of the River Slea in Lincolnshire, England, which opened in 1794. It ran from a junction with the River Witham, near Chapel Hill to the town of Sleaford through seven locks, most of which were adjacent to mills.
Interest in restoring the canal began in 1972, and navigation was restored to the first 8 miles (13 km) with the re-opening of Lower Kyme lock in 1986. The Sleaford Navigation Trust has been working towards restoring the whole waterway, and succeeded in purchasing the Sleaford end of the river bed in 2004. A short section at Sleaford was opened in 2010, following the installation of a lift bridge.
