Hillcrest is a suburb of the contiguous Auckland metropolitan area located in New Zealand. Since 2010, it has been under the jurisdiction of the Auckland Council, and is located in the North Shore, surrounded by Glenfield, Wairau Valley, Northcote and Birkenhead. The Auckland Northern Motorway passes to the east.

The name Hillcrest was given to the suburb by developer Ewen Allison. Prior to this, the area was referred to by the name Sunnybrae, which refers to Mr. Nicholson's farm in western Northcote.

The Hillcrest area is primarily uplifted Waitemata Group sandstone, that was deposited on the sea floor during the Early Miocene, between 22 and 16 million years ago. Prior to human settlement, the inland North Shore was a mixed podocarp-broadleaf forest dominated by kauri.

Hillcrest Creek is a stream that flows east through the suburb, entering the Waitematā Harbour at Shoal Bay, east of the Auckland Northern Motorway. Until the 1970s, the upper reaches of the creek were primarily swampland. A traditional recorded name for Hillcrest Creek is Wakatatere "The Drifting Canoe", a name which recalls an incident where a tapu drifted into the stream at high tide.

Hillcrest is bordered by Sunnybrae Road and Ocean View Road in the east, Archers Road and Glenfield Road in the west, and Pupuke Road in the south. The highest point in the suburb is the hill at Speedy Crescent, which is 98 metres (322 ft) above sea-level. The second highest point is an 88 metres (289 ft) hill to the south on Pupuke Road, referred informally by residents in the early 20th century as Clay Hill. The hill is the location of the Pupuke Road Reservoir and Pump Station.

Tāmaki Māori settlement of the Auckland Region began around the 13th or 14th centuries. While poor clay soils of the inland forest of the North Shore hindered Māori settlement, inland areas were used for harvesting resources from the forests.

Hillcrest was a part of the Mahurangi Block, an area purchased by the Crown on 13 April 1841. Land speculators made purchases in the area in 1843. In 1867 Alexander Wilson, bought 100 acres (40 ha) of land near modern-day Moore Street, cultivating the land for fruit growing. Wilson called his farmhouse Betsland. Wilson was joined by Mr. Nicholson, who established a 128 acres (52 ha) property in western Northcote that he called Sunnybrae.

In 1942 during World War II, a camp was established at Hillcrest to house the First Auckland Battalion of the New Zealand Army, later becoming Camp Hillcrest, a base for the United States Army. The suburb began developing as a suburb of Auckland in the 1960s and 1970s, after the construction of the Auckland Harbour Bridge. Sunnybrae Normal School was opened in 1966 as a school to support teachers training at nearby North Shore Teachers College (now the site of AUT North Campus). This was followed by Willow Park School, established in 1967.

Hillcrest covers 2.93 km (1.13 sq mi) and had an estimated population of 11,490 as of June 2024, with a population density of 3,922 people per km.
