Leif Edling (born 6 August 1963) is a Swedish musician, best known as the bassist, main songwriter and one of the founding members of the doom metal band Candlemass.

Edling started his musical career in the band Trilogy, then under the name of Toxic, as a singer together with Ian Haugland (later the drummer of Europe) in 1979.

In 1994, when Candlemass fell apart, Leif had started the band Abstrakt Algebra with Mats Levén on vocals and Mike Wead on guitar.

Since early 2014, Edling had been unable to tour with either Candlemass or Avatarium due to unspecified health problems, though believed to be chronic fatigue syndrome.

[4] A variety of replacement members were used, including Grave/Entombed bassist Jörgen Sandström and keyboard player Per Wiberg switching to bass.
