West Macquarie was an electoral district of the Legislative Assembly in the Australian state of New South Wales between 1859 and 1904, in the Bathurst region, named after the Macquarie River, being the western side of the river to the south of the town of Bathurst. 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] It was largely replaced by the new district of Blayney, which also absorbed parts of Hartley and The Macquarie. The rest of the district was absorbed by Yass.^[2][3][4]
