Turnfurlong (also known historically as Turn Furlong[1]) is an area of Aylesbury (where at the 2011 Census the population was included) in Buckinghamshire, England.

Turnfurlong Lane originated as a farm track that linked Walton hamlet with Bedgrove Farm and there was a small farmstead part way along the track called Turnfurlong, roughly in the location of what is now the back of Aylesbury Grammar School.

[2][3] Within the first ten years of the 20th century the new grammar school and the adjoining town cemetery were in place on the edge of Walton hamlet, and it is at about this time that the farmstead of Turnfurlong disappeared from period maps.

[2] Between the First World War and the Second World War Aylesbury was expanding in population and the stretch of Turnfurlong Lane between Walton and what is now Wendover Way was built up with three-bedroomed semi-detached family homes by the bookbinders Hazell, Watson and Viney for their employees.

Students learn modern languages such as French.The schools PTA(Parent Teacher Association) is currently named FoTJS.

The school is controlled by the Roman Catholic Diocese of Northampton and its motto is "I am special in God's eyes".
