The K-class ferries were a group of double-ended screw steam ferries run by Sydney Ferries Limited and its government successors on Sydney Harbour. The company introduced more than two dozen of the vessels from the 1890s through to the early twentieth century to meet the booming demand for ferry services across Sydney Harbour prior to the opening of the Sydney Harbour Bridge in 1932. The K-names were largely Australian Aboriginal names with their meanings listed in the table below.
