Wanneroo is an electoral district of the Legislative Assembly in the Australian state of Western Australia.
The district is located in the northern suburbs of Perth.
Wanneroo is a traditionally a marginal seat; it has been held by the government of the day on every occasion since its creation in 1989. However, at the 2021 state election, which resulted in a second consecutive landslide for Mark McGowan, the marginal trend was broken and Wanneroo became a very safe seat for the Labor Party.
