John Charles McIntosh, CBE, FRSA (born 6 February 1946) was Headmaster of The London Oratory School for 29 years until his retirement on 31 December 2006.

This was the theme of the paper he presented at the invitation of the then Prime Minister, Margaret Thatcher, at The State of Our Schools at an Education Seminar at Downing Street in 1986.

He has frequently found himself at odds with the Catholic Bishops of England and Wales, most notably in 1989, when the Westminster Diocese tried to browbeat his governors and trustees into abandoning the sixth form.

More recently he has been at odds with the Bishops over the issue of whether RE should be included in the English Baccalaureate: McIntosh believes that it should not.

In 2007–09 he was responsible for establishing a bilingual (English & French) primary education course involving a partnership between the local authority, the French government, Westminster Diocese and the governing body of a Catholic primary school; he now chairs the Bilingual Management Committee.

In April 2018 he was elected an honorary Professor of Professional Practice in Education at the University of Buckingham.

Under his headmastership, the London Oratory School was chosen for the education of the children of the Prime Minister, Tony Blair.
