Prison Without Bars is a 1938 British black-and-white crime film directed by Brian Desmond Hurst and starring Corinne Luchaire, Edna Best and Barry K. Barnes. It is set in a girl's reform school, and was based on a play by Gina Kaus, previously filmed in France as Prison sans Barreaux (1938). Corinne Luchaire starred in both versions.

A young progressive thinking woman becomes superintendent at a French girl's reformatory dominated by the harsh previous head. A young girl is blackmailed by her acquaintance over her love for the superintendent's fiancé, but is released to join him in the end, when all is revealed.

In The New York Times, Frank S. Nugent dismissed the film as "another prison picture, and while we would not want to pass too harsh a sentence upon it, neither can we fairly pretend that it is innocent": whereas, in December 1938, The Daily Telegraph selected it as one of their ten best films of the year.
