Full Confession is a 1939 United States proto film-noir, crime drama film made by RKO Radio Pictures.

Pat McGinnis (Victor McLaglen) murders a policeman and escapes by committing a more minor crime, for which he is arrested and jailed.

Pandro S. Berman of RKO bought the film rights to Leo Birinski's story in January 1939 intending to turn it into a vehicle for Chester Morris.

A key support part was given to Barry Fitzgerald, who had appeared in The Informer (1935) with McLaglen and had not made a film since Bringing Up Baby (1938); he had most recently been on Broadway in The White Steed.

[4] Full Confession is often regarded as a semi-remake of John Ford's The Informer (1935) starring the same leading man, Victor McLaglen.
