Batman vs. Teenage Mutant Ninja Turtles is a 2019 American animated superhero film directed by Jake Castorena and written by Marly Halpern-Graser. Inspired by the DC Comics and IDW Publishing comic book miniseries Batman/Teenage Mutant Ninja Turtles by James Tynion IV and Freddie Williams II, the story focuses on Batman, Robin, and Batgirl teaming up with the Teenage Mutant Ninja Turtles in order to save Gotham City from chaos at the hands of both Shredder and Ra's al Ghul. The film features the voices of Troy Baker, Eric Bauza, Darren Criss, Kyle Mooney, and Baron Vaughn.

In February 2019, it was announced that an animated adaptation of the comic book miniseries, Batman/Teenage Mutant Ninja Turtles, was in development, as a collaboration between Warner Bros. Animation, DC Entertainment, and Nickelodeon. The interdimensional aspect of the original comic story was omitted, in reverence to past superhero crossovers that establish both properties involved as existing in the same reality, with the additional goal of simplifying the story.

Batman vs. Teenage Mutant Ninja Turtles was produced for the direct-to-video market, and was released on both Blu-ray and Digital HD on June 4, 2019. It received positive reviews and grossed over $3.3 million from home video sales.
