Mullaloo is a northern beach suburb of Perth, Western Australia, located within the City of Joondalup.
Mullaloo is named after an Aboriginal word, believed to mean "place of the rat kangaroo". It was first recorded in 1919 as Moolalloo Point, but the spelling was later changed to Mullaloo. Urban development began in the late 1950s.
The Mullaloo Surf Life Saving club patrols around 4.5km of beach between Pinnaroo Point and Whitfords Point, between September and April. The club has row teams, swim teams, board teams and sprint teams.
Mullaloo has two schools, Mullaloo Beach Primary School and Mullaloo Heights Primary School.
