Fremantle Hospital is an Australian public hospital situated on South Terrace in central Fremantle, a suburb of Perth, Western Australia.

The building itself was originally a private residence called The Knowle, built in 1856 with both stone and labour from Fremantle Prison.

Facilities included 24-hour acute care, emergency department, a paediatric ward, a 66-bed psychiatric and psychogeriatric service.

[citation needed] The Hyperbaric Medicine unit has provided support services for divers in all of Western Australia and clinical services to residents mainly from the immediate area for over 20 years.
