O2 World is a multipurpose indoor arena located in the Friedrichshain neighborhood of Berlin, Germany. The arena opened in September 2008. Developed by Anschutz Entertainment Group, O2 Germany purchased the naming rights.
In January 2015 German car manufacturer Mercedes-Benz announced it had reached a deal with the arena management to rename the venue Mercedes-Benz Arena Berlin starting 1 July 2015. Between 2008 and 2015 the arena was known as O2 World Berlin due to sponsorship contract with Telefónica Germany, a telecommunications company.
