The State Shipping Service of Western Australia was a state government transport entity formed in 1912, in Western Australia, primarily to service the ports of North West Australia.
Originally named the State Steamship Service, it was renamed as the State Shipping Service in 1919, and again in 1979 as Stateships.
On 4 May 1912, the State Steamships Service was formed by the Scaddan government in response to requests for improved services along the North West Australian coast after the Adelaide Steamship Company withdrew its services. It was controlled by the Fremantle Harbour Trust between 1913 and 1918. In January 1919 it was renamed the State Shipping Service (SSS).
In November 1965, the SSS came under the responsibility of the newly formed Western Australian Coastal Shipping Commission. In January 1979 the service was rebranded Stateships.
In June 1995 the government announced that Stateships would cease operations, with the remaining three vessels sold. The government provided a subsidy to a privately operated service from Fremantle to Port Hedland, Broome and Wyndham until it ceased in 2013.
The Western Australian Coastal Shipping Commission, administered by the Department of Transport, continues to deal with ongoing former employee compensation claims.
The service's former offices in Fremantle are now used by the Spare Parts Puppet Theatre, and various artefacts from the service are housed in the Fremantle Maritime Museum.
The service originally provided transport for passengers, goods and , with passenger services ceasing in 1973.
