Mickey's Halloween Party is an annual Halloween-themed separate admission at the Disneyland Resort in Anaheim, California. An earlier event with the original name had been held in 1995 and 1996 at the Disneyland Park, but was not revived until 2005 at Disney California Adventure. Mickey's Halloween Party was considered to be a more family-friendly response to the scare-centered events Halloween Horror Nights, Knott's Scary Farm, and Six Flags Fright Fest. The event ran at Disney California Adventure through 2009, and returned to the Disneyland park starting in 2010. In 2019, the Party was moved back to Disney California Adventure and retitled Oogie Boogie Bash. Its new features included a water show at Pixar Pier called "Villainous".
