John Gunnar Levén (born October 25, 1963 in Stockholm, Sweden) is the bassist in the Swedish rock band Europe. Levén and vocalist Joey Tempest are the only band members who have performed on all of Europe's studio albums.
When Levén was 7 years old, he and his family moved to the suburbUpplands Väsby, where several members of Europe grew up. He joined the band in 1981, replacing Peter Olsson. In 1985 Levén was the one who suggested that Tempest should write a song based on an old keyboard riff that the vocalist had written around 1981-82. The result was the song "The Final Countdown".
