The Prude's Fall is a 1925 British silent drama film directed by Graham Cutts and starring Jane Novak, Julanne Johnston and Warwick Ward.The film was shot at Islington Studios, produced by a company that would soon develop into Gainsborough Pictures. It was an adaptation of a play by Rudolph Besier and May Edington with the screenplay written by Alfred Hitchcock. Its German title is Seine zweite Frau. It was also known by the alternative title of Dangerous Virtue.

It was not very well regarded. Iris Barry's review in the Daily Mail ran as follows: "An English picture, not of first-rate quality, but with an interesting cast."
