“See that on the screen? That there is the Dark Moon. It's a mysterious celestial body that has a pacifying effect on all of the ghosts in Evershade Valley.”

—Professor E. Gadd, Luigi's Mansion: Dark Moon

The Dark Moon is a crystal moon that is seen in Luigi's Mansion: Dark Moon and its HD remaster, Luigi's Mansion 2 HD. It resides in the sky over Evershade Valley and the five mansions in it. The Dark Moon exudes energy that calms the ghosts in Evershade Valley and causes them to be friendly. In the beginning of the game, King Boo builds up power from the gem on his crown and zaps the Dark Moon, shattering it into six pieces that are scattered across Evershade Valley and causing the ghosts to become hostile. The Dark Moon's destruction also causes ominous fog to cover the valley. One of the pieces lands between Professor E. Gadd's Bunker and the Gloomy Manor; the professor collects it before contacting Luigi. Each of the five remaining pieces is given to a Possessor, by King Boo, in each of Evershade Valley's five mansions: the Gloomy Manor, Haunted Towers, Old Clockworks, Secret Mine, and Treacherous Mansion. Luigi must recover all of these pieces and restore the Dark Moon in order to make the ghosts peaceful again. After a piece has been recovered, E. Gadd uses an invention to clean it in order to get rid of disruptive energy and restore its original properties; this also clears away some of the dark fog.

In Luigi's Mansion 3, a miniature version of the Dark Moon can be found inside the Drawing Room, accompanying a miniature model of the Gloomy Manor. Additionally, when King Boo gets dazed during his boss fight, purple moons spin around his head rather than typical stars.

In Super Mario Run, nine Dark Moons serve as the collectibles granted for completing the nine missions during the Luigi's Mansion 2 HD event. A statue based on the game is unlocked for every three Dark Moons earned.
