Three O'Clock in the Morning is a lost 1923 American silent drama film directed by Kenneth S. Webb and starring Constance Binney, Edmund Breese, and Richard Thorpe.
As described in a film magazine review, Elizabeth Winthrop becomes fascinated with cabaret life and makes friends who are objectionable to her parents. She resents her father's treatment of her friends and leaves home. She seeks work as a chorus girl in New York City and is aided by Hugo von Strohm, who unknown to her pays for her salary at the cabaret. Clayton Webster, her fiancé, objects to her work so she returns his engagement ring. Hugo invites her to a roadhouse and tries to force his attentions on her. On the way to the roadhouse, she is recognized by her mother and is rescued. Clayton is bound to leave by steamship to South America. Elizabeth arrives at the pier just as the ship is pulling away and wigwags that she loves him. He jumps overboard and swims ashore.
