King was an electoral district in the Australian state of New South Wales. It was created in 1904 as a result of the 1903 New South Wales referendum, which required the number of members of the Legislative Assembly to be reduced from 125 to 90. It largely replaced Sydney-King, losing a part to Darling Harbour. It was expanded to include parts of Sydney-Fitzroy and Sydney-Bligh. It also included Lord Howe Island, Montague Island and South Solitary Island.
