Great Ayton Friends' School (1841–1997) in Great Ayton, North Yorkshire, England, was an independent, co-educational, agricultural boarding school, run by the Religious Society of Friends (the Quakers). The school was situated on High Green on an estate of around 70 acres (280,000 m2) in a picturesque setting in the shadow of the Cleveland Hills. The River Leven (a tributary of the River Tees), ran through the school grounds and was bridged in several places.
