To Sir, With Love is a 1959 autobiographical novel by E. R. Braithwaite set in the East End of London. The novel is based on true events concerned with Braithwaite taking up a teaching post in a school there.

In 1967, the novel was made into a film, To Sir, with Love, starring Sidney Poitier and Lulu, and the film's title song became a number-1 hit that year. The setting for the film was changed from post-war London to the "swinging sixties", and, notwithstanding its success, Braithwaite had ambivalent feelings towards it, as he admitted in an interview with Burt Caesar conducted for a 2007 BBC Radio 4 programme entitled To Sir, with Love Revisited (produced by Mary Ward Lowery). Also in 2007, the novel was dramatized for Radio 4 by Roy Williams and broadcast in two parts, starring Kwame Kwei-Armah.
