The Doors were an American rock band formed in Los Angeles in 1965, comprising 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.

The band took its name from the title of the English writer Aldous Huxley's book The Doors of Perception, itself a reference to a quote by the English poet William Blake. After signing with Elektra Records in 1966, the Doors with Morrison recorded and released six studio albums in five years, some of which are generally considered among the greatest of all time, including their debut The Doors (1967), Strange Days (1967), and L.A. Woman (1971). Dubbed the "Kings of Acid Rock", they were one of the most successful bands of their time and by 1972, the Doors had sold over 4 million albums domestically and nearly 8 million singles.

Morrison died in uncertain circumstances in 1971. The band continued as a trio, releasing two more albums until disbanding in 1973. In 1978, they reformed for the album An American Prayer, which combined new music with Morrison's recitings of his poetry recorded in 1969 and 1970. They reunited again briefly in 1993 when they were inducted into the Rock and Roll Hall of Fame, and for several one-off projects in the 21st century. In 2002, Manzarek, Krieger, and Ian Astbury of the Cult on vocals started performing as "The Doors of the 21st Century". Densmore and the Morrison estate successfully sued them over the use of the band's name. After a short time as Riders on the Storm, they settled on the name Manzarek–Krieger and toured until Manzarek's death in 2013.

The Doors were the first American band to accumulate eight consecutive Gold LPs. According to the Recording Industry Association of America (RIAA), they have sold 34 million albums in the United States and over 100 million records worldwide, making them one of the best-selling bands of all time. The Doors have been listed as one of the greatest artists of all time by magazines including Rolling Stone, which ranked them 41st on its list of the "100 Greatest Artists of All Time".
