The A3 is a route designation of a major metropolitan arterial route through suburban Sydney, connecting the A8 at Mona Vale at its northern end, to Princes Highway at Blakehurst at its southern end. This name covers a few consecutive roads and is widely known to most drivers, but the entire allocation is also known – and signposted – by the names of its constituent parts: Mona Vale Road, Ryde Road, Lane Cove Road, Devlin Street, Church Street, Concord Road, Homebush Bay Drive, Centenary Drive, Roberts Road, Wiley Avenue and King Georges Road.

It is a major connector between most of the major radial routes emanating from central Sydney, and a major link between the northern and southern parts of the Sydney tolled orbital freeway. It is the most direct, although not necessarily the quickest, route across Sydney between the South Coast and the North Coast. It is one of only three road connections between the Northern Beaches region of Sydney and the rest of Sydney (the other two being routes A38 and A8.
