Strange Days is the second studio album by the American rock band the Doors, released on September 25, 1967 by Elektra Records, arriving eight months after their self-titled debut album. After the latter's successful release, the band started experimenting with both new and old material in early 1967 for their second record. Upon release, Strange Days reached number three on the US Billboard 200, and eventually earned a platinum certification from the Recording Industry Association of America (RIAA). It contains two Top 30 hit singles, "People Are Strange" and "Love Me Two Times".

Despite the album's failure to match the success of its predecessor, it was "arguably the one the band itself most appreciated musically and creatively", according to author David V. Moskowitz. Music journalist Stephen Davis considers Strange Days the best Doors album and "one of the great artifacts of the rock movement."
