Udo Jürgens (born Udo Jürgen Bockelmann, 30 September 1934, Klagenfurt, Carinthia, Austria) is an Austrian composer and singer of popular music whose career spans over fifty years. He has written more than 800 songs and sold over 100 million records. In 2007 he additionally obtained Swiss citizenship.

He is credited with broadening German-language pop music beyond the traditional postwar schlager in the 1960s by infusing it with a modern pop appeal; his exceptionally tuneful compositions and sophisticated arrangements attract fans of all ages, and even in his 70s he continues to fill the largest concert venues in Germany, Austria, and Switzerland.
