"Chelsea Girls" is the title track of Nico's 1967 debut album, Chelsea Girl. The song was written by Lou Reed and Sterling Morrison of the Velvet Underground, who Nico had collaborated with for their debut album the previous year. Running at just under seven and a half minutes long, "Chelsea Girls" is similar in style to a ballad, telling the stories of various residents at the hotel. It features guitar work from both Reed and Morrison, who wrote the song together, as well as a flute and string section, both of which are prominent throughout the song.
