Mugsy's Girls, also known as Delta Pi, is a 1984 film featuring pop singer Laura Branigan and Ruth Gordon. It tells the story of a sorority traveling to Las Vegas to participate in a mud wrestling competition. Their goal is to raise money to save their house. The film was released in theaters in 1985.

This is one of Gordon's final films (along with the three other films she made around this time that were released posthumously). She plays the sorority house-mother who ends up wrestling at the end. The film also features genre stars Eddie Deezen and Kristi Somers. Although Laura Branigan was quite famous as a singer by the time the filming began, she contributed no music to the film; most songs were performed by fellow cast member Joanna Dierck, who at one point was married to the film's writer and director Kevin Brodie.
