Torksey is a small village in the West Lindsey district of Lincolnshire, England. The population of the civil parish at the 2011 census was 875. It is situated on the A156 road, 7 miles (11 km) south of Gainsborough and 9 miles (14 km) north-west of Lincoln, and on the eastern bank of the tidal River Trent, which here forms the boundary with Nottinghamshire.

The Foss Dyke, or Fossdyke, connects the River Trent at Torksey to Lincoln, the county town of Lincolnshire, and may be the oldest canal in England that is still in use. It is usually thought to have been built around AD 120 by the Romans, but there is no consensus among authors. It was refurbished in 1121, during the reign of King Henry I, and responsibility for its maintenance was transferred to the city of Lincoln by King James I. Improvements made in 1671 included a navigable sluice or lock at Torksey, and warehousing and wharves were built at Brayford Pool in the centre of Lincoln.
