Steely Dan is an American jazz-rock band centered on core members Walter Becker and Donald Fagen. The band reached a peak of popularity in the late 1970s, with the release of seven albums blending elements of jazz, rock, funk, R&B, and pop. Rolling Stone magazine has called them "the perfect musical antiheroes for the Seventies."

Steely Dan toured from 1972 to 1974, but in 1975 became a purely studio-based act. In 1993, the group resumed playing live concerts; the early 21st century saw Steely Dan release two albums of new material, the first of which earned a Grammy Award for Album of the Year. They have sold more than 30 million albums worldwide.
