This List of navigation authorities in the United Kingdom is a list of links to any navigation authority in the United Kingdom, relating to any navigable waterway, aqueduct, canal, navigation, river or port.
- narrow canals, broad canals, or ship canals
- rivers which have been made navigable
- the Broads
- the navigable drains of The Fens.
The "Big Three"
- Canal and River Trust – A charity replacing British Waterways in managing the majority of the canals and many navigable rivers
- Environment Agency – environmental regulatory body, manages its waterways as part of its water management obligations.
- Broads Authority – manages its waterspace as part of the National Park Family. This is because no other national park has a navigation running through it and the "Sandford Principle" of conservation only would not be feasible.
