The New England New State Movement was an Australian political movement in the twentieth century. Founded as the Northern Separation Movement, the aim of the movement was to seek the secession of the New England region and surrounding areas from the State of New South Wales (NSW) and the establishment of a new State of New England. While popular at first and the subject of two Royal Commissions, the movement was unsuccessful, and was defeated at a referendum in 1967.

New England is a geographical region in the north of the state of New South Wales, Australia, about 60 km inland from the Tasman Sea. The area includes the Northern Tablelands and the North West Slopes regions. As of 2021, New England had a population of 185,560, with over a quarter of the people living in the area of Tamworth Regional Council.
