Sin City: A Dame to Kill For (also known as Frank Miller's Sin City: A Dame to Kill For) is a 2014 American action crime anthology film and follow-up to the 2005 film Sin City. Directed by Robert Rodriguez and Frank Miller, the script is written by Miller and is primarily based on the second book in the Sin City series by Miller, A Dame to Kill For.

One of the smaller plots of the film is based on the short story "Just Another Saturday Night", which is collected in Booze, Broads, & Bullets, the sixth book in the comic series. Two original stories ("The Long Bad Night" and "Nancy's Last Dance") were created exclusively for the film written by Miller. The film stars an ensemble cast including returning cast members Mickey Rourke, Jessica Alba, Rosario Dawson, Jaime King, Powers Boothe (in his final film role), and Bruce Willis. Newcomers to the series include Josh Brolin, Joseph Gordon-Levitt, Eva Green, Dennis Haysbert, Ray Liotta, Christopher Lloyd, Jamie Chung, Jeremy Piven, Christopher Meloni, Stacy Keach, Lady Gaga, Alexa Vega, Julia Garner, and Juno Temple.

The film was released on August 22, 2014, on 2D, 3D and RealD 3D. Unlike the first film, A Dame to Kill For underperformed at the box office, grossing $39.4 million against its $65 million production budget, and received mixed reviews from film critics.
