Trolls is a 2016 American animated jukebox musical comedy film produced by DreamWorks Animation and distributed by 20th Century Fox, based on the Good Luck Trolls dolls created by Thomas Dam. The film was directed by Mike Mitchell and co-directed by Walt Dohrn (in his feature directorial debut), from a screenplay by the writing team of Jonathan Aibel and Glenn Berger, based on a story by Erica Rivinoja. It stars the voices of Anna Kendrick, Justin Timberlake, Zooey Deschanel, Russell Brand, James Corden, John Cleese and Gwen Stefani. The film follows two trolls named Poppy (Kendrick) and Branch (Timberlake) who go on a quest to save their village from destruction by the Bergens, giant creatures who eat Trolls to be happy.

Trolls premiered at the BFI London Film Festival on October 8, 2016, and was theatrically released in the United States on November 4, by 20th Century Fox. The film received generally positive reviews from critics and grossed $347 million worldwide against its $125 million budget. It received an Academy Award nomination for Best Original Song for "Can't Stop the Feeling!".

It was one of three DreamWorks films to be the last to be distributed by 20th Century Fox alongside The Boss Baby and Captain Underpants: The First Epic Movie. Following NBCUniversal's acquisition of DreamWorks Animation in 2016, Universal Pictures began distributing DreamWorks's films, starting with How to Train Your Dragon: The Hidden World (2019).

A sequel, Trolls World Tour, was released on April 10, 2020, while a third film, Trolls Band Together, was released on November 17, 2023.
