The Horn Blows at Midnight is a 1945 comedy fantasy film directed by Raoul Walsh, and starring Jack Benny.

Following its poor box-office, Benny often exploited the film's failure for laughs over the next 20 years in his radio and television comedy series The Jack Benny Program, making the film known to those audience members who had never seen it. The Horn Blows at Midnight was Benny's last feature film as a lead; he continued to do cameo appearances in films for many years.
