Fantastic Beasts: The Crimes of Grindelwald is a 2018 fantasy film directed by David Yates and written by J. K. Rowling. The sequel to Fantastic Beasts and Where to Find Them (2016), it is the second instalment in the Fantastic Beasts film series and the tenth overall in the Wizarding World franchise. It features an ensemble cast including Eddie Redmayne, Katherine Waterston, Dan Fogler, Alison Sudol, Ezra Miller, Zoë Kravitz, Callum Turner, Claudia Kim, William Nadylam, Kevin Guthrie, Jude Law, and Johnny Depp. Set in 1927, it follows Newt Scamander and Albus Dumbledore as they attempt to take down the dark wizard Gellert Grindelwald while facing new threats in a more divided wizarding world.

A second Fantastic Beasts film was announced in October 2014, and Rowling confirmed in July 2016 that she had completed the script. Depp was cast in November 2016, causing some controversy due to domestic violence allegations made against him. Law signed on in April 2017. Principal photography began in July 2017 at Warner Bros. Studios, Leavesden, in England. Filming also took place in London, Switzerland, and Paris, and wrapped in December 2017.

Fantastic Beasts: The Crimes of Grindelwald premiered in Paris on 8 November 2018 and was released worldwide on 16 November 2018 by Warner Bros. Pictures. It grossed $654.9 million worldwide, making it the tenth highest-grossing film of 2018. It became the lowest-grossing instalment of the Wizarding World franchise upon release, which it remained until the release of its sequel, Fantastic Beasts: The Secrets of Dumbledore, in 2022. It received negative reviews from critics, as it was viewed to have been filled with too many characters and "overburdened" with sequel-dependent details. The film was nominated for two British Academy Film Awards, in the categories of Best Production Design and Best Special Visual Effects. The sequel, Fantastic Beasts: The Secrets of Dumbledore, was released in April 2022.
