The Cumberland Highway is a 34-kilometre (21 mi) long urban highway located in Sydney, New South Wales, Australia. The highway links the Pacific Highway (A1/B83) and Pacific Motorway (M1) at Pearces Corner, Wahroonga in the northeast with the Hume Highway (A22/A28) at Liverpool in the southwest.

The entire length of Cumberland Highway is designated route A28.

The name of the highway is derived from the Cumberland Plain and Cumberland County. The name Cumberland was conferred on the County by Governor Phillip in honour of Ernest Augustus, Duke of Cumberland.

The original western Sydney Bypass was Ring Road 5, which ran from the Pacific Highway and the Hume Highway with Parramatta in between. In 1974, Ring Road 5 was superseded by State Route 55. The growth of Sydney's west had instead turned it into a primary arterial with huge increase in freight traffic.

In August 1988, the highway was finally completed to supersede the Church Street/Woodville Road route as the major connection between the Pacific and Hume Highways. The highway was named "Cumberland Highway" after completion. State Route 77 was proclaimed and allocated to the entire length of the highway.

Metroad 7 replaced State Route 77 in June 1993 and the highway was designated by the Federal Government as an interim National Highway in 1994 until the completion of Westlink M7. When Metroad 7 was introduced, it went along Heathcote Road to the then Metroad 1 (now A1) at Heathcote. The southern section of Heathcote Road was replaced by the then Metroad 6 (now A6) in 1998, and Metroad 7 was therefore truncated to the end of Cumberland Highway at Liverpool.
