Fremantle is a Western Australian suburb located in Perth at the mouth of the Swan River, and is situated 18 kilometres (11 mi) from the Perth central business district.

One of the original settlements of the Swan River Colony established in 1829 is within the area known today as this suburb.

Fremantle is bounded by the Swan River to the north and north-west, the Indian Ocean to the west, South Street to the south, and the suburbs of East Fremantle and White Gum Valley to the east.

The central part of the suburb extends eastwards to include Royal Fremantle Golf Club and a suburban area south of Marmion Street and west of Carrington Street.

All services are operated by Swan Transit and Transdev WA as part of the Transperth network.
