Mixtape is a pre-debut extended play (EP) by South Korean boy group Stray Kids.

The EP was released digitally and physically on January 8, 2018 by JYP Entertainment and distributed through Genie Music.

On December 28, 2017, the boy group posted a track list image about the pre-debut album Mixtape release date.

The image created a dark atmosphere by overlapping the silhouettes of the nine Stray Kids members and the shape of a cassette tape reminiscent of a mixtape.

The album release date was announced with the phrase ‘2018.01.08’ in the center of the cassette tape.
