Carry On Nurse is a 1959 British comedy film, the second in the series of 31 Carry On films (1958–1992). Of the regular team, it featured Joan Sims, Kenneth Williams, Kenneth Connor and Charles Hawtrey, with Hattie Jacques and Leslie Phillips. The film was written by Norman Hudis based on the play Ring for Catty by Patrick Cargill and Jack Beale. It was the top-grossing film of 1959 in the United Kingdom and, with an audience of 10.4 million, had the highest cinema viewing of any of the "Carry On" films. Perhaps surprisingly, it was also highly successful in the United States, where it was reported that it played at some cinemas for three years. The film was followed by Carry On Teacher 1959.

Carry On is a British comedy franchise comprising 31 films, four Christmas specials, a television series and stage shows produced between 1958 and 1992. Produced by Peter Rogers, the Carry On films were directed by Gerald Thomas and starred a regular ensemble that included Sid James, Kenneth Williams, Charles Hawtrey, Joan Sims, Kenneth Connor, Peter Butterworth, Hattie Jacques, Terry Scott, Bernard Bresslaw, Barbara Windsor, Jack Douglas, and Jim Dale. The humour of Carry On was in the British comic tradition of music hall and bawdy seaside postcards. The success of the films led to several spin-offs, including four Christmas television specials (1969–1973), a 1975 television series of 13 episodes and three West End stage shows that also toured the United Kingdom.
