Blackwood Interchange (Welsh: Cyfnewidfa Coed Duon) is a bus station located in the town centre of Blackwood, Caerphilly, South Wales. It is situated on Gordon Road adjacent to the High Street.

The existing Blackwood Bus Station redeveloped by Caerphilly County Borough Council in 2007. The project cost an approximate £2.4 million.

During development, traders in the town centre voiced concerns that "customers will be put off walking through the market when contractors move in" however Councillors reassured concerned individuals with the prospect of a reduction in the business rate for affected businesses.

Architect Geraint Jones, unusually, was an internal developer from within Caerphilly Council's own department, at a time where most civic developments in the UK are designed by private practices.

The redevelopment of Blackwood Bus Station was judged by Caerphilly Council as successful, helping to end the anti social behaviour associated with the previous concrete structure station, and it has encouraged the subsequent development of the town in the form of new retail units on its periphery and the new Sirhowy Enterprise Way area.

The 2007 redevelopment won a number of awards nationally, including:

The bus station is a glass façade terminal building including café, waiting area, canteen, offices and welfare facilities.

The stand doors provide access to buses, which park next to the gate on arrival, and then reverse out on departure. It is fully covered from the weather.
