Donald Jay Fagen is an American musician who was the co-founder, lead singer, co-songwriter, and keyboardist of the band Steely Dan, formed in the early 1970s with musical partner Walter Becker. In addition to his work with Steely Dan, Fagen has released four solo albums, beginning with The Nightfly in 1982, which was nominated for seven Grammys.

The Nightfly is the debut solo studio album by American singer-songwriter Donald Fagen. Produced by Gary Katz, it was released October 1, 1982, by Warner Bros. Records. Fagen is best known for his work in the group Steely Dan, with whom he enjoyed a successful career since the 1970s. The band separated in 1981, leading Fagen to pursue a solo career. Although The Nightfly includes a number of production staff and musicians who had played on Steely Dan records, it was Fagen's first release without longtime collaborator Walter Becker.
