"Elegia" is a piece composed by Peter Hook, Gillian Gilbert, Stephen Morris, and Bernard Sumner for the British rock band New Order. Unusually for New Order, it is an instrumental and a waltz. It can be found on their third studio album, Low-Life (1985). Elegia is Latin for elegy; New Order has stated that the song was written in memory of Ian Curtis, lead singer of the band's former incarnation, Joy Division. The full 18 minute version of "Elegia" was released in 2012.
