Nena feat. Nena, also known as 20 Jahre – Das Jubiläums-Album is a studio album by German pop singer Nena. It contains new versions of her hits, many with her band also called Nena, some of them duets with other singers including Kim Wilde, Joachim Witt and Udo Lindenberg. The album was first released in 2002 with a red cover and reissued with a blue cover in 2003. Both releases exist in either standard or limited edition, the latter being supplemented with a bonus CD of live tracks. The songs on the bonus CD are also reworked, suggesting that Nena may have planned to update more of her back-catalogue, although there have been no further releases in this vein.

Gabriele Susanne Kerner, better known by her stage name Nena, is a German singer who rose to international fame in 1983 as the lead vocalist of the band Nena with the Neue Deutsche Welle song "99 Luftballons". In that same year, the band re-recorded this song in English as "99 Red Balloons". Nena's re-recording of some of the band's old hit songs as a solo artist, produced by the co-composer of most of them, her former Nena band colleague and keyboard player Uwe Fahrenkrog-Petersen, rekindled her solo career in 2002. Combined with the success of the Nena band years, she has sold over 25 million records, making her the most successful German pop singer in chart history.
