Hybrid Theory is the debut album by the American rock band Linkin Park, released on October 24, 2000 through Warner Bros. Records.

Recorded at NRG Recordings in North Hollywood, California, and produced by Don Gilmore, the album's lyrical themes deal with problems lead vocalist Chester Bennington experienced during his adolescence, including drug abuse and the constant fighting and divorce of his parents. Hybrid Theory takes it's title from the previous name of the band as well as the concept of music theory and combining different styles. Four singles were released from the album: "One Step Closer", "Crawling", "Paper cut", and "In the End", all of them being responsible for launching Linkin Park into mainstream popularity. While "In the End" was the most successful of the four, all of the singles in the album remain some of the band's most successful songs to date. Although "Runaway", "Points of Authority", and "My December" from the special edition bonus disc album were not released as singles, they were minor hits on alternative rock radio stations thanks to the success of all of the band's singles and the album.
