Fairham Brook is a 16-mile-long (26 km) tributary of the River Trent that flows through Leicestershire and Nottinghamshire in England.

It initially flows in a northerly direction, and then turns west passing through the villages of Widmerpool, and Bunny.

The brook joins the River Trent near Silverdale, on the outskirts of Nottingham near Clifton Bridge.

[5] Fairham Brook acts as the arterial watercourse and has been designated as main river from Clifton to its confluence with the Trent.

This is one of the lower bands in the five part framework scale, which ranges from high, good, and moderate, through to poor and finally bad.
