The Divergent Series: Insurgent (simply known as Insurgent) is a 2015 American dystopian science fiction action film directed by Robert Schwentke, based on the 2012 novel Insurgent, the second book in the Divergent trilogy by Veronica Roth. It is the sequel to the 2014 film Divergent and the second installment in The Divergent Series, produced by Lucy Fisher, Pouya Shabazian and Douglas Wick, with a screenplay by Brian Duffield, Akiva Goldsman and Mark Bomback. Schwentke took over from Neil Burger as director, with Burger serving as the executive producer of the film. Along with the first film's returning cast, led by Shailene Woodley and Theo James, the sequel features supporting actors Octavia Spencer, Naomi Watts, Suki Waterhouse, Rosa Salazar, Daniel Dae Kim, Jonny Weston, Emjay Anthony, and Keiynan Lonsdale.

The plot of Insurgent takes place five days after the previous installment and continues to follow Dauntless soldier Tris Prior; Tris and Four, her Dauntless instructor, are on the run after evading a coup from Erudite faction leader Jeanine and the rest of her faction. The faction system in post-apocalyptic Chicago is crumbling, and everyone is desperate for power — and answers. Filming began on May 27, 2014, in Atlanta, Georgia, before concluding on September 6, 2014.

Some considered the film to be an improvement over its predecessor, with the visual style, action sequences, and Woodley's performance being singled out for praise; criticism focused on the film's storyline and derivative nature.
