St Trinian's is a 2007 British comedy film and the sixth in a long-running series of British films based on the works of cartoonist Ronald Searle and set in St Trinian's School. The first five films form a series, starting with The Belles of St. Trinian's in 1954, with sequels in 1957, 1960, 1966 and a reboot in 1980. The release of 2007, 27 years after the last entry, and 53 years after the first film, is a rebooting of the franchise, rather than a direct sequel, with certain plot elements borrowed from the first film.

Whereas the earlier films concentrated on the adults, this film gives the school pupils greater prominence. St Trinian's is an anarchic school for uncontrollable girls run by eccentric headmistress Camilla Dagey Fritton (the reboot continues the tradition, established by Alastair Sim in the original film, of casting a male actor to play the female headmistress, with Rupert Everett inheriting the role).

St Trinian's received mixed reviews but remains one of the highest-grossing British independent films of the last thirty years.
