Mark William Lanegan (November 25, 1964 – February 22, 2022) was an American singer, songwriter and poet. First becoming prominent as the lead singer for the early grunge band Screaming Trees, he was also known as a member of Queens of the Stone Age and The Gutter Twins. He released 12 solo studio albums as well as three collaboration albums with Isobel Campbell and two with Duke Garwood. He was known for his baritone voice, which was described as being "as scratchy as a three-day beard yet as supple and pliable as moccasin leather" and has been compared to Tom Waits, Leonard Cohen and Nick Cave.

Lanegan began his musical career in 1984 in Screaming Trees, with whom he released seven studio albums and five EPs before their disbandment in 2000. During his time with the band, he also began a solo career and released his first solo studio album, The Winding Sheet, in 1990. He then released 10 more solo albums, which received critical recognition but only moderate commercial success. Following the end of Screaming Trees, he became a frequent collaborator of Queens of the Stone Age and was a full-time member between 2001 and 2005 during the Songs for the Deaf and Lullabies to Paralyze eras.

Lanegan collaborated with various artists during his career. In the 1990s, he and Kurt Cobain recorded an album of Lead Belly covers that was ultimately never released. He also joined Layne Staley and Mike McCready in the band Mad Season, and formed the alternative rock group The Gutter Twins with Greg Dulli in 2003, as well as contributing to releases by Moby, Bomb the Bass, Soulsavers, Tinariwen, The Twilight Singers, Manic Street Preachers, and Unkle, among others.

Lanegan struggled with addiction to drugs and alcohol throughout his life but had been sober for over a decade at the time of his death. Encouraged by his friend Anthony Bourdain, he released the memoir Sing Backwards and Weep in 2020. He followed this up in 2021 with the memoir Devil in a Coma, which focused on his near-death experience with COVID-19. He and his wife Shelley Brien left the U.S. in 2020 and settled in the Irish town of Killarney, where he died two years later at the age of 57. No cause of death was revealed.
