Ghost is a Swedish rock band known for combining costumed theatricality, heavy metal, and arena rock. Formed in Linköping in 2006, the band released their debut album, Opus Eponymous in 2010, which earned them international recognition. This was followed by Infestissumam in 2013 and in 2015 by Meliora, which reached number one in Sweden and number eight in the US. This was followed by the albums Prequelle in 2018 and Impera in 2022.

Known for their costumed on-stage presence, Ghost's members, except for the lead vocalist, are known as "Nameless Ghouls". The lead-singer has performed under the persona of "Papa Emeritus", a character known for its "demonic anti-pope" imagery, while changing this for subsequent tours.

In 2017, the identity of the lead-singer was revealed to be Tobias Forge after several musicians who had worked with him on the Ghost project started legal action over royalties. The single, "Cirice", earned the band a Grammy Award for Best Metal Performance in 2016, while they have been nominated for several Swedish Grammis awards.
