Market Street, Fremantle is the location of the Fremantle Post Office in Fremantle, Western Australia. It commences opposite the Fremantle railway station, intersects with High Street and joins with South Terrace at an intersection with Bannister Street. It is also part of the boundary of the Fremantle West End Heritage area. The street was named with the intention of there being a market place at what is now the railway station site, however markets were never established. The National Hotel and Princess Theatre did later locate along the street.
