The Division of Macarthur is an Australian electoral division in the state of New South Wales. The division is named after John Macarthur and his wife Elizabeth, who were both pioneers of Australia's wool industry. The main products and work in the electorate are in the fruit and vegetable production, lucerne and fodder crops, wine, dairy cattle and horse-breeding. Ahead of the 2016 federal election, ABC psephologist Antony Green listed the seat in his election guide as one of eleven which he classed as "bellwether" electorates.
