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 from a screenplay by 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 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!".

The film was one of the last three DreamWorks films to be distributed by 20th Century Fox alongside The Boss Baby and Captain Underpants: The First Epic Movie (2017). Following NBCUniversal's acquisiton of DreamWorks Animation in 2016 and Disney's acquisition of 21st Century Fox in 2019, as well as the name changing of 20th Century Fox into 20th Century Studios in 2020, Universal Pictures began distributing films from DreamWorks, 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.
