Andrea Berg (born 28 January 1966) is a German singer in the Schlager genre.

Berg was born in Krefeld. As a child she would experiment with performing short sketches at carnivals and other celebrations. She later played with a band, and also worked backstage on stage set-up and drove the band's van. During this time she supported herself working as a nurse in the intensive care and oncology departments of a hospital.

Berg's musical career began in 1992 when the producer Eugen Romer obtained a cassette of her performing. He was enthused by her voice, and within a week the first tracks had been recorded for her debut album Du bist frei ("You Are Free"), which contained the singles "Kilimandscharo" and "Schau mir noch mal ins Gesicht". Romer also produced her second album, Gefuhle ("Feelings"), which proved her commercial breakthrough. The singles from the album, "Wenn du mich willst, dann kub mich doch" and "Einmal nur mit dir alleine sein", were hits. The album also featured one of her most popular songs, "Die Gefuhle haben Schweigepflicht".

In 1997 she released her third album, Traume lugen nicht ("Dreams Don't Lie"), which reached #71 on the German album charts. The first single, "Warum nur traumen", was a #1 hit on some radio playlists and stayed in the charts for 15 weeks.

In summer 1998 the birth of her daughter Lena-Maria was followed by the release of the album Zwischen tausend Gefuhlen ("Between a Thousand Feelings"), with twelve songs. The singles from this album were "Diese Nacht soll nie enden", "Insel der Nacht" and "Jenseits der Zartlichkeit" (1999).

The next album was Weil ich verliebt bin ("Because I'm in Love") in 1999, with the single "Vielleicht ein Traum zu viel". This reached #3 in the ZDF-Hitparade in November 1999. Berg also reached #3 in "Hits of the Year" in January 2000 and was #1 for several weeks in the German airplay charts.

In October 2001 a best-of was released, featuring twelve of her most popular songs. The album went five-times platinum and has been in the German top 100 album chart for a record-breaking stay of over 300 weeks. Two million copies have been sold.

She has at times had as many as four releases in the German charts simultaneously.

She won the ECHO award in the German-language Schlager category in 2003, 2004, 2005 and 2007. From 2002 to 2007 she won Germany's prestigious Goldene Stimmgabel six times consecutively, as well as the Amadeus Austrian Music Award for best Schlager album in 2004 and 2005. Her CD Nah am Feuer went gold.

The 2006 album Splitternackt ("Stark Naked") went straight to #1 in Germany and remained there for several weeks.

The hit "Du hast mich tausendmal belogen" reached #2 in the GEMA chart of collected international sales.

Berg is known not only for her music but also increasingly for her stage outfits. She favours short miniskirts, suspenders, and knee-highs reminiscent of Pretty Woman. She has been quoted (in the Neuen Post) as saying "When you reach 40 you do have to make an effort to keep the men looking in your direction". ("Wenn man auf die 40 zugeht, muss man sich eben anstrengen, damit die Manner einem noch hinterherschauen.")

From 2002 to 2004 Berg was married to the Schlager singer Olaf Henning. In 2007 she married the football manager and hotelier Ulrich Ferber. They currently live together with her daughter in Aspach, Baden-Wurttemberg.
