The Australian Electoral Commission (AEC) is the federal government agency in charge of organising, conducting and supervising federal elections and referendums.

The Australian Electoral Commission is also responsible for seat boundaries and redistributions, and maintains the Commonwealth electoral roll. Under the Joint Roll Arrangements, the AEC maintains the electoral roll for the whole of Australia. This roll is used by the state and territory Electoral Commissions to conduct their elections.

The AEC also plays a leading role in electoral education and industrial voting (votes on industrial action).
