Turnbull High School is a co-educational comprehensive secondary school located in Bishopbriggs, East Dunbartonshire, Scotland. The school was named after William Turnbull, Bishop of Glasgow from 1448 to 1454, and founder of the University of Glasgow in 1451, of which he was the first Chancellor. Whilst enrollment is open to pupils of all religious denominations and none, the School's religious ethos emphasises practice of Roman Catholic moral values both in the church and in the community, with its own Chaplain and many associated charitable and community-based activities undertaken.

Bishopbriggs is a town in East Dunbartonshire, Scotland. It lies on the northern fringe of Greater Glasgow, approximately 4 miles (6 km) from the city centre. Historically in Lanarkshire, the area was once part of the historic parish of Cadder - originally lands granted by King William the Lion to the Bishop of Glasgow, Jocelin, in 1180. It was later part of the county of Lanarkshire, and then an independent burgh from 1964 to 1975. Today, Bishopbriggs' close geographic proximity to Glasgow now effectively makes it a suburb and commuter town of the city.
