Mystic Manor () is a dark ride attraction in the Mystic Point area of Hong Kong Disneyland.
 Unlike Disneyland's Haunted Mansion attraction and its counterparts in other Disney parks, Mystic Manor has a lighthearted, fantasy-based theme with no references to departed spirits or the afterlife, due to differences in traditional Chinese culture.
 The attraction does feature several references to the Haunted Mansion, such as a Medusa changing portrait, a conservatory, and the busts that turn to follow visitors as they move.
 References to other Disney attractions include several figures similar to those from The Enchanted Tiki Room in the Tribal Arts room.
 The Manor's exterior design is inspired by the now-demolished Bradbury Mansion that stood at 147 North Hill Street in Los Angeles' Bunker Hill, designed by Samuel Newsom and Joseph Cather Newsom, who also designed the still-standing Carson Mansion in Eureka, California.
