Grimsby Dock Tower is a famous maritime landmark in North East Lincolnshire. It was built in 1867 with the purpose of containing a 30,000 UK gallon (136 m³) water reservoir, which was originally used to provide hydraulic power to the lock gates and cranes of Grimsby Docks.

The tower was designed by Mr J W Wild and was based around the design of the Palazzo Pubblico in Sienna.

The tower is 309 ft (94 m) high, 28 ft (8.5 m) wide at the base and its walls are 4 ft (1.2 m) thick, and Grade I listed.

Local legend has it that the tower was built on a foundation of cotton wool, although when asked, locals never say it has been disproved or proved. During the Second World War, there were plans to knock it down, due to it acting as a beacon for German aeroplanes.

The tower no longer has any commercial use, although twice a year, people abseil down the side to raise money for charity. There is a chance (for a fee) to climb the structure to see the amazing views over the whole of Grimsby and Cleethorpes.

There is a model of the Grimsby Dock Tower entirely constructed of Lego in Legoland in Windsor. While the tower itself is correct, a large building has been incorrectly added to the base of the tower.
