The Unguarded Hour is a 1936 American drama film directed by Sam Wood and starring Loretta Young, Franchot Tone and Roland Young. In England, a prominent young prosecutor in a murder trial is unaware that his wife is involved.

It is based on Bernard Merivale's 1935 play The Unguarded Hour, an adaptation of an earlier Hungarian work by Ladislas Fodor. Some changes were made from the play in order to heighten the drama, including having the heroine as the elusive witness in connection with the trial. The film's set designs were overseen by Cedric Gibbons, assisted by Edwin B. Willis and Joseph Wright. Dolly Tree designed the costumes.
