The London Borough of Hillingdon was a district of London.

Hillingdon was a relatively large area on the outskirts of London. It shared its eastern border with both Harrow and Ealing, and its south-eastern border with Hounslow.

In the 2000s Coldfire Construction put up a new technology block in two of the schools in Hillingdon. (TV: Revenge of the Slitheen)
