The Children's Court of Western Australia is a state court that hears cases involving children (aged 10 to 17 years) accused of committing criminal offences.^[1] It was originally called the Perth Children's Court when it was created in 1907^[2] by the State Children's Act, but became known Children's Court of Western Australia when the Children's Court of Western Australia Act 1988^[3] was passed.

The Perth Children's Court is located at 160 Pier Street, Perth, although children's court cases are heard in other courthouses throughout the state.

The current purpose-built Court building was constructed by Cooper & Oxley and officially opened on 9 June 1992. Previously the Court was housed in St George's Hall in Hay Street until it was re-located in 1977 to the former East Perth Primary School buildings.
