John Gunnar Levén (born 25 October 1963) is a Swedish bassist in the rock band Europe.

Levén and vocalist Joey Tempest are the only band members who have performed on all of Europe's studio albums.

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.

After Europe went on hiatus in 1992, Levén recorded and toured with bands like Brazen Abbot, Clockwise, Last Autumn's Dream, Southpaw, Europe colleague John Norum and former Black Sabbath / Deep Purple vocalist Glenn Hughes.

Europe reunited in 2003, and Levén co-wrote the single "Always the Pretenders" from the 2006 album Secret Society, with Tempest.
