Two Rocks is an outer suburb at the northern edge of Perth, the state capital of Western Australia, located 61 kilometres (38 mi) northwest of the city's central business district.

It is part of the City of Wanneroo local authority and represents the furthest northern extent of the Perth metropolitan region.

A major landmark in the suburb is a large limestone sculpture of King Neptune by American sculptor Mark Le Buse, a remnant of the defunct Atlantis Marine Park, which operated between 1981 and 1990.

As well as being the former location of Atlantis Marine Park, the suburb was also a hub of Alan Bond's failed Yanchep Sun City development plan in the 1980s.

[6] In recognition of this, the Sun City precinct, which encompasses the marina, shopping centre, the King Neptune sculpture, and the former site of Atlantis Marine Park, was added to the State Register of Heritage Places in January 2023.
