Band ohne Namen (English translation Band Without Name, also known as B.O.N., previously known under the name Die Allianz) was a duo composed of Guy Gross and Claus Capek, both from Germany. They are most famous for their hip-pop record Boys, which charted in many European countries in the year 2000.

The original version of Boys as featured in their debut album No. 1 consisted of German lyrics interrupted by an English chorus. The single became a hit after it was translated fully into English, which spurred their next album B.O.N. in the USA, which was an all-English version of No. 1.
