HMAS Tasmania (H25) was an Admiralty S class destroyer of the Royal Australian Navy (RAN). Built for the Royal Navy during World War I, the ship was not completed until 1919, and spent a year commissioned but not operational in British service before being transferred to the RAN at the start of 1920. The destroyer's career was uneventful, with almost all of it spent in Australian waters. Tasmania was decommissioned in 1930, and was sold for ship breaking in 1937.
