Blayney was an electoral district of the Legislative Assembly in the Australian state of New South Wales, created in 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 Hartley, The Macquarie and the abolished seat of West Macquarie, and named after and including Blayney. It was abolished in 1913 and partly replaced by Lyndhurst.[2][3][4]
