Candlemass is a Swedish doom metal band formed in Upplands Väsby, a suburb of Stockholm, in 1984 by bassist, songwriter, and bandleader Leif Edling, alongside drummer Matz Ekström. The band has had a defining influence on doom metal, with the epic doom genre itself taking its name from their debut album Epicus Doomicus Metallicus. Along with Pentagram, Saint Vitus, and Trouble, Candlemass has been recognized as one of the "big four of doom metal".

After releasing five full-length albums and extensively touring throughout the 1980s and early 1990s, Candlemass disbanded in 1994 but reunited three years later. Following another breakup in 2002, the band reformed in 2004 and has continued to record and perform ever since.
