# List of navigation authorities in the United Kingdom

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.
These include:

* rivers which have been made navigable
* the Broads
* the navigable drains of The Fens.

## Examples of navigation authorities
### The "Big Three"

* Canal and River Trust – 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.
