The Pure Hell of St Trinian's is a 1960 British comedy film directed by Frank Launder and starring Cecil Parker, George Cole, Joyce Grenfell and Eric Barker.

The Monthly Film Bulletin wrote: "The Pure Hell of St. Trinian's demonstrates that reputable producers are just as capable of turning out third-rate British farces as any mushroom growth B-picture studio.

Given a script without a vestige of originality, Frank Launder's capacity as a director is revealed as correspondingly tired and easily satisfied; his film, despite a promising opening, could hardly be more shapeless or laborious.

The experienced actors give embarrassing performances, and the monstrous girls themselves, uprooted from their proper environment, are left like their elders to cope as well as they can against a series of arbitrary backdrops – army encampments, desert islands, Arab market-places, that sort of thing.

With the school reduced to smouldering ashes, mysterious child psychologist Cecil Parker takes charge of the tearaways, in league with white-slaving sea captain Sidney James.
