All for Mary is a 1955 British comedy film directed by Wendy Toye and starring Nigel Patrick, David Tomlinson, Jill Day and Kathleen Harrison. It was written by Peter Blackmore, Paul Soskin and Alan Melville based on the successful West End play of the same title by Kay Bannerman and Harold Brooke, and was produced by Paul Soskin Productions for the Rank Organisation.

The film had an original copyright notice with a renewal in 1983.

Two young bachelors take separate skiing holidays at the same resort. Clive Morton and "Humpy" Miller have nothing whatsoever in common –except for one thing: both men fall for the hotel proprietor's daughter Mary. Clive (a debonair soldier and sportsman) gets quickly into his stride, whilst poor "Humpy" – a clumsy, incongruous fellow – looks on dumbly. However, "Humpy" has a secret weapon: Miss Cartwright, his former nanny, who arrives just as the pair are quarantined in the hotel attic after contracting chicken pox. Quickly realising Humpy's predicament, she skillfully arranges for the removal of the opposition, leaving the way clear for "Humpy".

The film was based on a play which debuted in 1954. Kathleen Harrison and David Tomlinson played key roles and the production ran for nine months in London.

Variety called it "a nonsensical comedy".

The film was announced in January 1955 as part of Rank's slate for that year.

It was directed by Wendy Toye, who had joined the Rank Organisation after being under contract to Alex Korda. She later stated "they got me and they didn’t know what to do with me much and I think they had All for Mary on their hands and thought as she had been a theatre director that had been in the theatre, maybe that would be good subject for her."

Troye had a difficult relationship with producer Paul Soskin who she called "ridiculous".
