Alexander Klaws (born 3 September 1983) is a German singer, songwriter, and actor. Born and raised in Ahlen, North Rhine-Westphalia, he came into prominence after becoming the winner of the debut season of the television series Deutschland sucht den Superstar, the German version of Idol series, in 2003 and as a participant in the television special World Idol the same year.

Klaws was immediately signed to SonyBMG after winning DSDS, and released his debut single "Take Me Tonight" in 2003. Upon its release, the single topped the German and Swiss Singles Chart, eventually becoming one of the best-selling singles of 2002 in German-speaking Europe. The same year, Klaws released his album Take Your Chance, which contained elements of a pop and became a major commercial success. The following year, his second album Here I Am reprised this success. In 2005, Klaws parted ways with his management and musical mentor Dieter Bohlen and developed a more rock-oriented sound with the release of his third album, Attention!.
