Cadbury Heath is a residential suburb in South Gloucestershire, England.

It is in Oldland parish in the eastern fringe of the Bristol Built-up Area, 5 miles (8 km) east of Bristol city centre, and borders the neighbourhoods of Longwell Green, Oldland Common, Warmley and Kingswood.

Much of the area was developed in the immediate post-war period as a low-rise council estate suburb, with a neighbourhood centre including a primary school, pub and community hall.

The estate gained the nickname "Banjo Island" due to the layout of the streets around Park Crescent.

[2] For elections to South Gloucestershire Council, it is in the Parkwall and Warmley electoral ward.
