The Normanhurst School was an independent, non-denominational, day and boarding school for girls that operated in Ashfield, in the Inner Western suburbs of Sydney, New South Wales, Australia.^[1]

Despite being non-denominational, the Normanhurst school maintained close links with St John's Anglican Parish, which was situated in the vicinity of the school.^[2]

The Normanhurst School was established in 1882 by Ellen Clarke, who was an English national.^[2] Clarke was principal of the school from its founding in 1882 to 1893.^[2] In 1884, her sister Marian Clarke arrived in Australia from England to join the faculty, and founded Abbotsleigh the following year.^[3]

At its foundation, the school operated out of a cottage located on Bland Street, Ashfield.^[2] Later as the school expanded, it moved to another larger campus in Ashfield at the intersection of Orpington and Chandos streets (pictured right).^[2]

Through the initiative of the then headmistress, Evelyn Tildesley, the Normanhurst School became a founding member of the Headmistresses’ Association of NSW (which has since become the Association of Heads of Independent Girls' Schools) in 1916.^[4]

The school ceased operations in 1941.^[1]
