"Demons" is a song by American pop rock band Imagine Dragons.

Within two years of its release, more than 4.1 million copies were sold in the United States, making it the eighth most downloaded song in rock history at the time.

[7] An MTV report on the "Demons" music video stated that it would "fit nicely with the artful imagery of 'It's Time' and the thoroughly out-there puppet grappling of 'Radioactive'.

[4] Various characters with personal hardships are depicted, including a grieving daughter, a man with Marfan syndrome who stares at himself in a mirror, a victim of parental abuse and a military veteran carrying his wounded comrade.

The clip ends with a dedication to Tyler Robinson (1995–2013), a fan of the band who died at the age of 17 in March 2013 following a battle with cancer.
