Nena was a German Neue Deutsche Welle band formed in West Berlin in 1981. In 1983 and 1984, their German-language song "99 Luftballons" reached number one in the singles charts of countries around the world.

Neue Deutsche Welle is a genre of West German rock music originally derived from post-punk and new wave music with electronic influences. The term was first coined by Dutch radio DJ Frits Spits on the popular nationwide radio station Hilversum 3, which was very popular among German listeners. Soon after that, the term was used in a record-shop advertisement by Burkhardt Seiler in an August 1979 issue of the West German magazine Sounds. It was then used by journalist Alfred Hilsberg in an article about the movement titled Neue Deutsche Welle — Aus grauer Städte Mauern in Sounds in October 1979.
