Gun-Marie Fredriksson (Swedish: [maˈriː ˇfreːdrɪkˌsɔn] (listen); 30 May 1958 – 9 December 2019) was a Swedish pop singer, songwriter, pianist and painter, who was best known internationally as the lead vocalist of pop rock duo Roxette, which she formed in 1986 with Per Gessle. The duo achieved international success in the late-1980s and early-1990s with their albums Look Sharp! (1988) and Joyride (1991), and had six top two hits on the Billboard Hot 100: "The Look", "Listen to Your Heart", "Dangerous", "It Must Have Been Love", "Joyride" and "Fading Like a Flower (Every Time You Leave)".
Fredriksson had a successful career in her native country prior to forming Roxette. She was a member of punk group Strul, a band which created their own music festival in 1979. Strul's dissolution led to the creation of her next project, the short-lived MaMas Barn, after which she began releasing solo work. Her first album, Het vind, was issued in 1984, followed by Den sjunde vågen in 1986 and ... Efter stormen in 1987. Roxette's international breakthrough coincided with a period of inactivity for Fredriksson as a solo artist, punctuated only by the release of the non-album single "Sparvöga" in 1989. Subsequent solo albums included Den ständiga resan (1992) and I en tid som vår (1996).
In 2002, after fainting at home, Fredriksson was diagnosed with a brain tumour. During her rehabilitation, she continued to record music as a solo artist, resulting in The Change in 2004 and Min bäste vän in 2006, as well as the non-album single "Där du andas" in 2008—her first and only solo number one single in Sweden. She and Gessle later reunited to record more albums as Roxette, who embarked on a worldwide concert tour. She also continued to record as a solo artist in her native Sweden, releasing Nu! in 2013.
She is also known as Gun-Marie Fredriksson and Gun-Marie Bolyos.
Fredriksson died on 9 December 2019. She was diagnosed with a brain tumor in 2002, and died following a 17-year battle with cancer at the age of 61. A private funeral, with only her family and closest friends in attendance, took place at an undisclosed location. Among the tributes expressed to Fredriksson was a statement from King Carl XVI Gustaf of Sweden, who said "We have been struck by the sad news that singer Marie Fredriksson has passed away. For many in our country, even in my family, her music is closely associated with memories from particularly important moments in life."
