CGM Arena, Multi-purpose arena in the Oberwerth sports park, Koblenz, Germany

CGM Arena is a multi-purpose hall in Koblenz that holds up to 5,000 people and covers about 3,400 square meters of space. The building features high ceilings, six skylights that bring in natural light, and flexible layouts that can be reconfigured for different types of events.

Planning for a hall on the Oberwerth began in 1969, and construction started on 1 March 1990. Mayor Willi Hörter opened the Sporthalle Oberwerth on 18 January 1992 with a sports gala, during Koblenz's 2000th-anniversary celebrations. It became the Conlog Arena on 1 January 2013, the CGM Arena on 1 January 2018, and took the name EPG Arena on 1 January 2025.

The EPG Arena sits in the Sportpark Oberwerth, south of Koblenz's old town across the Rhine; the hall has rooms for conferences, a side hall with a sprint track and long-jump pit, and a weight room. Six transverse light bands in the roof let daylight into the 3,400 m² interior.

The hall's roof lets daylight in through six transverse light bands. It has hosted world championships in dance, rock 'n' roll, motorcycle trials and ring tennis, and European championships in fencing and karate. The TV show "Wetten, dass..?" was broadcast from here on 20 March 1993.
