Malcolm James McCormick, known professionally as Mac Miller, was an American rapper, singer-songwriter, and record producer. Miller began his career in Pittsburgh's local hip hop scene in 2007, at the age of 15. In 2010, he signed a record deal with independent label Rostrum Records and released his breakthrough mixtapes K.I.D.S. (2010) and Best Day Ever (2011). Miller's debut studio album, Blue Slide Park (2011), became the first independently distributed debut album to top the US Billboard 200 since 1995.

K.I.D.S. is the fourth mixtape by American rapper Mac Miller. It was released by Rostrum Records on August 13, 2010, through DatPiff. The title is a reference to the 1995 drama film Kids, which is quoted throughout the mixtape. It was later commercially released on April 29, 2020. A deluxe version was released on its 10th anniversary and includes two new tracks.
