Wellington was an electoral district of the Legislative Assembly in the Australian state of New South Wales, created in 1859 and named after and including Wellington. It replaced part of Wellington (County). It was abolished in 1904 due to the 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] The district was largely replaced by an expanded The Macquarie, while parts also went to Liverpool Plains and Mudgee.[2][3][4]
