Joy Division were an English rock band formed in 1976 in Salford, Greater Manchester. Originally named Warsaw, the band consisted of singer Ian Curtis, guitarist and keyboardist Bernard Sumner, bass player Peter Hook, and drummer Stephen Morris.

Formed by Sumner and Hook after the two attended a Sex Pistols gig, Joy Division moved beyond their punk roots to develop a sound and style that made them one of the pioneers of the post-punk movement. Their self-released 1978 debut EP, An Ideal for Living, drew the attention of the Manchester television personality Tony Wilson, who signed the group to his independent label, Factory Records. Joy Division's debut album Unknown Pleasures, recorded with producer Martin Hannett, was released in 1979 to critical acclaim. As the band's popularity grew, Curtis suffered from personal problems that included depression, a failing marriage, and epilepsy, and found it increasingly difficult to perform live concerts, during which he sometimes suffered seizures.

In May 1980, on the eve of the band's first American tour, Curtis, aged 23, committed suicide. The band's second and final album, Closer, was released two months later; the album and preceding single "Love Will Tear Us Apart" became the band's highest charting release. After Curtis's death, the remaining members continued as New Order and achieved critical and commercial success. Although their career spanned less than four years, Joy Division have continued to exert a vast influence on a variety of subsequent artists.
