Westfield Warringah Mall, previously known as Warringah Mall, is a large indoor/outdoor shopping centre in the suburb of Brookvale in the Northern Beaches region of Sydney.

Warringah Mall opened on 4 April 1963 and was developed by Hammerson Group and was the second largest Australian shopping centre at the time with Chadstone Shopping Centre being the largest. The centre was partially built on the site of 'Brookvale House', which was built by Sydney Alexander Malcolm in 1883 and was sold in 1961 to the Hooker Investment Corporation. Warringah Mall contained around 50 stores, including David Jones, Nock & Kirby, Franklins and Woolworths. Ten years later, the centre saw the opening of a new Grace Bros store which was upgraded from a homemakers store in 1973. The same year, a fire broke out in the original Woolworths store, killing two female workers. Fifty more speciality stores have also opened, followed by the opening of the Hoyts Twin Cinema Complex in the early 1980s.

Warringah Mall was featured in the movie BMX Bandits with two young BMX experts, P.J. (Angelo D'Angelo) and Goose (James Lugton), who meet Judy (Nicole Kidman), who was working as a trolley collector. In the mid-1980s, a Target store was opened along with 20 specialty stores. To commemorate the Australian Bicentenary, Warringah Shire Council commissioned local sculptor Victor Cusack to create a central fountain for the mall. Entitled "Pacific Family", it was unveiled by Deputy Shire President Julie Sutton on 23 November 1988.

Warringah Mall was included in the sale of Hammerson's Australian property portfolio to AMP Capital in 1994. In 1998, Warringah Mall underwent stage 2 of redevelopment and was officially opened in December 1999. The development included a new food court and entertainment precincts with the opening of Hoyts and Galaxy World, it also included the opening of new stores next to the food court including Rebel Sport, Surf Dive ‘n' Ski and Warringah Mall Library which opened near Hoyts. The old areas also had a makeover which was to introduce a quality homewares precinct with retailers such as Wheel & Barrow and Dick Smith Powerhouse in 2000. Franklins closed in 2001 and was by replaced by Priceline Pharmacy. The same year German global discount supermarket Aldi opened outside the centre on the corner of Cross and Green Street. Aldi previously had plans to open inside the centre but was rejected by AMP Capital due to disputes between rival supermarkets Coles and Woolworths.

In March 2003 Westfield Group purchased a 25 per cent shareholding, this was increased to 50 per cent in October 2012. AMP Capital and the Westfield Group swapped interests in seven centres, including Warringah Mall which became a 50/50 joint venture between the two companies. As part of the deal, centre management transferred from AMP to Westfield with the centre rebranded Westfield Warringah Mall. In July 2014, as part of a restructure of the Westfield Group, it came under the control of the Scentre Group.

In January 2015, in preparation for the $310 million redevelopment up to ten stores were closed and relocated. Two carparks were closed and demolished in February 2015 and hoardings were erected around the centre court area. Around that time Myer began its refurbishment, shrinking from three levels to two. The store continued to trade during the refurbishment until February 2016 when it temporarily closed to allow for works to continue.

The $310 million redevelopment began in August 2015 with stage one of the redevelopment completed by June 2016. Westfield Warringah Mall unveiled its 1200 spaces five-level car park and a new fresh food court which was opened by My Kitchen Rules 2015 winners Will and Steve on 30 June 2016.

Stage two of the redevelopment was completed by November 2016 with the grand opening on 17 November 2016. The two-level Myer was officially opened by Australian model Jennifer Hawkins.

This stage two development features two new mini majors a two-level H&M, Cotton On Mega and an Anaconda store, a new two-level parallel mall linking Myer and the existing centre (built over an existing carpark) and a new refurbished centre court with a new look "Pacific Family" fountain and a water feature and a surfboard-inspired sculpture known as "Whitewash" (made from 43 chrome surfboards) by Laura Enever outside Myer. 70 new stores (including 50 fashion stores including H&M and Sephora) were added to the centre.

Plans for the $226 million redevelopment will include a new relocated Hoyts Cinema on level 3, addition of 35 food outlets including licensed premises together, 15 speciality retailers, 10 small outlets and one major store. They will be located on the three levels as part of the additional 10,000sqm of extra retail space. The existing food court on level 1 will be expanded to the south with addition of six food court outlets. The restaurant precinct on level two will feature views overlooking Brookvale Creek and the Warringah golf course. The redevelopment will add modifications to existing specialty stores and the existing Kmart store on the ground level are also planned. The number of parking spaces will increase to a total of 5,093. This development follows the 2008 master plan of the centre. A 14-month timeline has been estimated for completion of the project. The plans for the centre had been decided in May.

Westfield Warringah Mall has 131,589m² of floor space. The major retailers include David Jones, Myer, Big W, Kmart, Coles, Woolworths, Bunnings, Cotton On, H&M, TK Maxx, JB Hi-Fi, Rebel, Anaconda and Hoyts Cinema

• On 29 August 1969, security guard Joseph Charles Coffman was shot and killed by an unknown assailant. It appeared that Coffman was attacked from behind with a blow to the neck, and then shot through the shoulder with what appeared to have been his own revolver. 17,000 cigarettes were found at the scene, so Coffman may have interrupted a robbery in progress. Les Howarth, a 15 year old youth of Balgowlah, accompanied Coffman on his patrol, who was asleep in the security service car at the time of the shooting. A vehicle was seen speeding away from the mall, and a stolen car was found abandoned 17 kilometres away in Ku-ring-gai Chase National Park.
