Heathen Chemistry is the fifth studio album by the English rock band Oasis, released on 1 July 2002 by Big Brother Records.

The album was written and recorded with a back-to-basics sound with a more rock feel to it; the more crude and simple sound differs from the musical grandiosity of their previous records, Be Here Now (1997) and Standing on the Shoulder of Giants (2000), being more comparable to their early work.

Heathen Chemistry is notable for being the first Oasis album recorded with guitarist Gem Archer and bassist Andy Bell, who both joined the band after work on previous album Standing on the Shoulder of Giants had been completed. It would also prove to be last album to feature the band's longtime drummer, Alan White, who left in early 2004, with Noel Gallagher claiming White's commitment to the band was not adequate. He was effectively replaced with Ringo Starr's son, Zak Starkey. The album was released to generally mixed reviews from critics.

The name "Heathen Chemistry" was taken from a second hand T-shirt that Noel had stumbled across.

Heathen Chemistry was recorded during 2001–early 2002 and is the first Oasis album to have significant writing contributions from members other than chief songwriter Noel Gallagher. Front man Liam Gallagher contributed three songs, and new bassist Andy Bell and rhythm guitarist Gem Archer contributed one song each as well.

Although most of the song's instrumentation was complete by mid-to-late 2001, Noel indicated that the release date of the album was being needlessly delayed by Liam's apparent reluctance to lay down his vocal parts at recording sessions, and went on to state that he was "livid" at the lack of work being done:

Despite the setbacks during the recording process, when the album was finally complete Noel was confident that it was the group's second best album to date, behind their debut Definitely Maybe.
