The word 'Fremantle' can apply to a few different things:
- City of Fremantle, the local government area (LGA)
- Fremantle (suburb), the suburb in the LGA
- Division of Fremantle, the federal division of the Australian House of Representatives
- Electoral district of Fremantle, a state lower house electoral district
But most importantly, the 'port city', whose temporal or spatial boundaries are not exact.
