Yes, The Nightmare Before Christmas has a massive presence in Disneyland, primarily through the famous Haunted Mansion Holiday overlay. Every year, typically from late August through early January, Jack Skellington and his friends "wreck the halls" of the Haunted Mansion, transforming the classic spooky attraction into a festive mash-up of Halloween and Christmas. The ride features an original soundtrack, appearances by Jack, Sally, and Oogie Boogie, and a massive, real gingerbread house in the ballroom scene that changes design every year. In 2026, visitors should note that while the overlay is a beloved tradition, the attraction often undergoes brief closures in January and August to install or remove the decorations. Beyond the ride, you can find a wealth of Nightmare Before Christmas themed merchandise in the New Orleans Square shops and occasionally encounter Jack and Sally for character meet-and-greets during the Halloween Time and Holiday seasons. It remains one of the most popular seasonal transformations in any Disney park worldwide.
