Rough Night in Jericho is a 1967 American Western film in Techniscope, directed by Arnold Laven and starring Dean Martin, George Peppard and Jean Simmons.

The picture was based on the novel The Man in Black, written in 1965 by Marvin H. Albert, who also co-wrote the screenplay.

Sharpshooting from a safe distance, Flood wounds the coach's driver, Ben Hickman, who is brought to town by the only passenger, a gambler named Dolan.

She was once Flood's lover when he came to Jericho to restore law and order, but now she hates the man who has seized power in the town.

Flood forms a lynch mob that hangs a man who dared confront one of his gang, then dynamites the home of general store owner Ryan, another townsman who tried to organize a secret meeting.
