Operation Bullshine is a 1959 British colour comedy film directed by Gilbert Gunn and starring Donald Sinden, Barbara Murray and Carole Lesley. The working title of the film was Girls in Arms that features as a marching song in the film. Gunn had filmed Girls at Sea the previous year. The new title, based on an American euphemism for a very British word with the same meaning (bullshite), comes from the frenzied activity preparing for their brigadier's surprise inspection. The film features 1956 Olympic gold medallist Judy Grinham as a physical training instructor.

The film was later also released in the US in 1963 by Seven Arts Productions.
