Northern Expressway, also known as the Fatchen Northern Expressway,^[3][4] is a 21 kilometre long controlled-access highway in Adelaide, South Australia. Since March 2020, the North–South Motorway continues west of Port Wakefield Highway and intersects the Port River Expressway to reach the harbour at Port Adelaide. These are the northernmost two parts of the North–South Corridor.

Cycling is not permitted on the Expressway. The Stuart O'Grady Bikeway is a sealed shared cycling and walking path adjacent to the eastern side of the expressway. The northern end connects to the on-ramp from Two Wells Road to the Gawler Bypass Road, and the southern end is adjacent to Port Wakefield Road at Mill Road.
