Welcome to My Nightmare is the debut solo studio album by American rock musician Alice Cooper, released on February 28, 1975. It is his only album for the Atlantic Records label in North America; in the rest of the world, it was released on the ABC subsidiary Anchor Records. Welcome to My Nightmare is a concept album. Played in sequence, the songs form a journey through the nightmares of a child named Steven. The album inspired the Alice Cooper: The Nightmare TV special, a worldwide concert tour in 1975, and his Welcome to My Nightmare concert film in 1976. The ensuing tour was one of the most over-the-top excursions of that era. Most of Lou Reed's band joined Cooper for this record.

Alice Cooper is an American rock singer and songwriter whose career spans sixty years. With a raspy voice and a stage show that features numerous props and stage illusions, including pyrotechnics, guillotines, electric chairs, fake blood, reptiles, baby dolls, and dueling swords, Cooper is considered by many music journalists and peers to be "The Godfather of Shock Rock". He has drawn equally from horror films, vaudeville, and garage rock to pioneer a macabre and theatrical brand of rock designed to shock audiences.
