"Strange Days" is a song by the Doors, released in 1967 as the opening track on the album of the same name. Along with other album tracks, it was composed before the date it was recorded; a live performance recorded in May 1966 was captured on the 2016 album London Fog 1966. The track is also recognised as one of the earliest showcases for the use of the Moog synthesizer.

The Doors were an American rock band formed in Los Angeles in 1965, with vocalist Jim Morrison, keyboardist Ray Manzarek, guitarist Robby Krieger and drummer John Densmore. They were among the most influential and controversial rock acts of the 1960s, primarily due to Morrison's lyrics and voice, along with his erratic stage persona and legal issues. The group is widely regarded as an important figure of the era's counterculture.
