633 Squadron is a 1964 war film directed by Walter Grauman and starring Cliff Robertson, George Chakiris, and Maria Perschy. The plot, which involves the exploits of a fictional World War II British fighter-bomber squadron, was based on the 1956 novel of the same name by former Royal Air Force officer Frederick E. Smith, which itself drew on several real RAF operations. The film was produced by Cecil F. Ford for the second film of Mirisch Productions UK subsidiary Mirisch Films for United Artists. 633 Squadron was the first aviation film to be shot in colour and Panavision widescreen.

The squadron is led by Wing Commander Roy Grant, a former Eagle Squadron pilot (an American serving in the RAF before the US entered the war).
