Eight Crazy Nights, also known as Adam Sandler's Eight Crazy Nights, is a 2002 American adult animated Hanukkah musical comedy-drama film directed by Seth Kearsley (in his feature directorial debut), written by Adam Sandler, Allen Covert, Brooks Arthur, and Brad Issacs, and produced by Sandler, Covert, and Jack Giarraputo. It stars Sandler in his first voice-acting role, alongside future wife Jackie Titone, Austin Stout, Rob Schneider, Kevin Nealon, Norm Crosby, and Jon Lovitz. The film is animated in the style of television holiday specials and, unlike most mainstream holiday films, centers on Jewish characters and the holiday of Hanukkah, as opposed to the Christian celebration of Christmas.

The title is taken from a line in Sandler's series of songs called "The Chanukah Song" that compares the gift-giving traditions of Christmas and Chanukah: "Instead of one day of presents, we get eight crazy nights!" A new version of "The Chanukah Song" also plays over the film's closing credits.

Produced by Sandler's production company Happy Madison Productions (as its first animated film), Eight Crazy Nights was released in the United States on November 27, 2002, by Columbia Pictures. The film grossed $23.8 million and received negative reviews from critics.
