"It is with profound sorrow that we announce the loss of Tim Bergling, also known as Avicii. He was found dead in Muscat, Oman, this Friday afternoon local time," said his press representative in a statement.
"The family is devastated and we ask everyone to please respect their need for privacy in this difficult time. No further statements will be given."
One of Sweden's biggest music exports, Avicii's first hit 'Levels' was released in 2011 and propelled him into the mainstream and made him an international superstar.
The Stockholm native became one of the world’s most successful DJs and helped lead the global boom in electronic music.
His smash hit 'Wake me up' became the first song to be played more than 200 million times on Spotify in the history of the music streaming giant in 2014.
Avicii shocked many fans in 2016 when he announced his early retirement, following cancellations of shows due to health problems. In 2017 he returned to the studio with the release of six-track EP Avīci (01).
