Camperdown was an electoral district of the Legislative Assembly in the Australian state of New South Wales, created in the 1904 re-distribution of electorates following the 1903 New South Wales referendum, which required the number of members of the Legislative Assembly to be reduced from 125 to 90.[1] It consisted of parts of Annandale and the abolished seats of Darlington, Newtown-Camperdown and Newtown-Erskine. It was named after and included the inner Sydney suburb of Camperdown. In 1920, with the introduction of proportional representation, it was absorbed into the multi-member electorate of Balmain.[2][3][4]
