Sister Act 2: Back in the Habit is a 1993 American musical comedy film, directed by Bill Duke, and released by Touchstone Pictures. It is the sequel to the 1992 film Sister Act, and is loosely based on the life of Crenshaw High School choir instructor Iris Stevenson. The story sees Whoopi Goldberg reprising her role as Deloris van Cartier, as she finds herself coming to the aid of her nun friends who need her help to save her old school. Maggie Smith, Kathy Najimy, Wendy Makkena, and Mary Wickes also reprised their roles in the sequel.

The film performed well at the box office, but was less commercially successful than its predecessor, and initially received generally negative reviews from critics. However it has proved popular with fans and has become a cult classic. It starred Lauryn Hill in her breakout role, as well as Sheryl Lee Ralph, Alanna Ubach, and Jennifer Love Hewitt. Gospel singer Erica Campbell of the duo Mary Mary, R&B singer Ryan Toby of the group City High, and The War and Treaty singer Tanya Trotter, also made appearances as members of the film's choir.
