Hotel Transylvania 2 is a 2015 American animated monster comedy film produced by Columbia Pictures and Sony Pictures Animation in association with LStar Capital, animated by Sony Pictures Imageworks, and distributed by Sony Pictures Releasing. Directed by Genndy Tartakovsky and written by Robert Smigel and Adam Sandler, it is the second installment in the Hotel Transylvania franchise, serving as the sequel to Hotel Transylvania (2012).

The film takes place several years after the events of the first film. Mavis and Johnny have a young son named Dennis, whose lack of any vampire abilities worries both Mavis and his maternal grandfather Dracula for differing reasons. When Mavis and Johnny travel to Johnny's hometown in Santa Cruz, California, Drac calls his friends to help him make Dennis a vampire, much to Mavis's dismay.

Original voices from the first film — Sandler, Andy Samberg, Selena Gomez, Kevin James, David Spade, Steve Buscemi, Molly Shannon, Fran Drescher, Rob Riggle, Sadie Sandler, Jonny Solomon, Luenell, Chris Parnell, and Jon Lovitz — returned for the sequel, with Keegan-Michael Key replacing CeeLo Green as Murray. New additions to the cast include Asher Blinkoff, Nick Offerman, Megan Mullally, Dana Carvey, and Mel Brooks.

The film was released theatrically on September 25, 2015, by Sony Pictures Releasing under the Columbia Pictures label. It received mixed to positive reviews and grossed over $474 million worldwide on an $80 million budget, and won a 2016 Kids' Choice Awards for Favorite Animated Movie. A sequel, Hotel Transylvania 3: Summer Vacation, was released in 2018. This film was dedicated to Rama Messinger, who died during production.
