Jenny Be Good is a 1920 American silent romance drama film directed by William Desmond Taylor and starring Mary Miles Minter, based on a novel by Wilbur Finley Fauley and adapted for the screen by Julia Crawford Ivers. It is the last of Minter's films to also feature her older sister Margaret Shelby in a supporting role. As with many of Minter's features, it is believed to be a lost film.
