The A4, A44 and M4 are a collection of arterial routes in Sydney, New South Wales that connect the Inner West of Sydney with the outer western suburbs.

The A4 and M4 mostly follows what was previously National Route 32 from the Western Distributor in the CBD, west to the Great Western Highway at Lapstone. Both the A4 and M4 sections were known as Metroad 4 until 2013, which in turn replaced the previous Sydney stretch of National Route 32 in September 1992 while the A44 was known as State Route 44 until 2013.

Between 2019 and 2023, the progressive opening of WestConnex resulted in route allocation of M4 along newly opened sections, and former bypassed sections of A4 redesignated as A44. The last route redesignation was in November 2023 with the opening of Rozelle Interchange, the last component of the WestConnex.

The names "M4", "A44" and "A4" are just the route allocations for the route as a whole. In fact, the M4 route runs along a whole series of motorways with the A44 running parallel along non-motorway roads until they converge west of Anzac Bridge. East of here is the Western Distributor, the only section of the A4 route, even though the Western Distributor is also a controlled-access highway (i.e. like a motorway but with lower speed limits).

The roads from east to west are:

• A4 section:
  • Western Distributor
• A44 section:
  • Victoria Road
  • The Crescent
  • City West Link
  • Dobroyd Parade
  • Wattle Street
  • Great Western Highway/Parramatta Road (West of Wattle Street Intersection)
• M4 section:

  • Western Motorway
