Écailles de lune is the second studio album by French blackgaze band Alcest, released on March 26, 2010 by Prophecy Productions. It is the first Alcest album featuring Winterhalter on drums. Although it continues in the direction started with the first album Souvenirs d'un autre monde, Écailles de lune marks a darker, louder transition into shoegaze, while also coming back to the band's black metal origins as it features harsh vocals like those found on their second release Le Secret.
