The M8 Motorway is a 15.2-kilometre (9.4 mi) tolled dual carriageway motorway in Sydney that is designated the M8 route marker. It consists predominantly of tunnels and includes tunnel connections to the future Western Harbour Tunnel and the M6 Motorway.

As of November 2023^[update], the M8 Motorway comprises only the WestConnex M8 tolled motorway which opened in multiple stages:

• The first stage to open (previously known as the New M5) was a 9-kilometre (5.6 mi) section that links the M5 Motorway at Kingsgrove to the St Peters Interchange at St Peters.^[2]
• The second and third stages to open (previously known as part of the M4–M5 Link and later M4–M8 Link) were extensions of WestConnex M8 from St Peters to Leichhardt where it meets the M4 Motorway and the Rozelle Interchange to allow connections with Victoria Road and the Anzac Bridge.

These sections were constructed as part of the WestConnex project, and WestConnex tolls are applied.

Future sections of the M8 are being constructed as the Western Harbour Tunnel, which will connect the M8 at Rozelle Interchange to the A8 at Neutral Bay.^[3] Separate to WestConnex, it is expected to open in 2028.
