Red Bull BC One is an annual international breakdancing series sponsored by the energy drink company Red Bull. It is an individual (or 'one on one') b-boy competition (as opposed to a crew competition). The main event is a knockout tournament featuring sixteen b-boys competing in one-on-one battles decided by a panel of five judges. The winners of worldwide regional knockout tournaments preceding the main event, along with the prior year's top finishers as well as wild card selections, comprise the final group of 16.

The event has been held in a different city and country every year. In 2004 it was held in Biel, Switzerland, 2005 in Berlin, Germany, 2006 in São Paulo, Brazil, 2007 in Johannesburg, South Africa, 2008 in Paris, France, and 2009 in New York City, USA. It has been announced that the 2010 event will be held in Tokyo, Japan.

An official Red Bull BC One DVD was released for the 2004 and 2005 events. The production of the DVDs has been criticized as the live music played during the competition is dubbed over and certain portions of the battles are edited out. The 2006 DVD was released in Europe so it is only available in PAL format. From 2006 and on, Red Bull stopped releasing DVDs and made the videos available online for free.
