Donald in Maui Mallard, known as Maui Mallard in Cold Shadow in North America, is a platform game released in 1995 for the Mega Drive, in 1996 for the Super NES and PC, and in 1998 for the Game Boy.

It was developed and released by Disney Interactive for the Mega Drive, with Eurocom and Bonsai Entertainment developing the SNES and Game Boy versions afterward. Despite being the original, the Mega Drive version was only released in Europe and Brazil and never saw a North American Sega Genesis version due to Nintendo securing an exclusive publishing contract for the game in North America, but the Mega Drive version did see an American release but only as a Sega Channel exclusive. The game was one of the first games to be released under the Disney Interactive label.

The game stars Donald Duck under the identity of an anthropomorphic duck detective named Maui Mallard, who adopts the name "Cold Shadow" when he dresses up in ninja garb. For the North American versions of the game, all Donald Duck references are omitted for unknown reasons and the main character is only known as Maui Mallard. Though the end of the game informed the player to look forward to Maui's next adventure, there have been no other appearances of Maui Mallard or Cold Shadow in any medium.
