Derby Highway is a highway linking Great Northern Highway in Western Australia with the town of Derby.^[1] It is a 42-kilometre-long (26 mi) 2-lane single carriageway. In the town of Derby, its name changes to Loch Street, where it becomes a 2-lane divided carriageway.

The RAAF Curtin inactive air force base is situated adjacent to Derby Highway near the intersection of Great Northern Highway. The base has been previously^[when?] used as a refugee detention centre and civilian airport, but is not presently used for any functional purpose.

Derby Highway is the western terminus of the popular Gibb River Road. It is also a useful access for many local fishing "secret spots" at the mouth of the Fitzroy River, with one of the better known ones being the Cuttings.^{[citation needed]}

A staged reconstruction of the highway has been taking place in recent years.^[when?] So far, approximately 15 kilometres (9.3 mi) of the highway has been reconstructed and widened, with plans for the remainder to be completed in the near future.
