Ethias Arena, Concert and event venue in Hasselt, Belgium.

Ethias Arena is an event venue in Hasselt that hosts concerts, festivals, and trade fairs with flexible capacity. The building contains a main performance hall, private suite areas, public plaza spaces, and dedicated backstage facilities for performers and crew.

Construction of the arena began in March 2004 and it opened six months later at a cost of €11.7 million. It was built as an extension of the Grenslandhallen trade-fair halls, which had needed more exhibition space since a 2000 study. In 2002 a stage tower, meeting rooms and a retractable stand had already allowed concerts and musicals there. The Sportpaleis Group, now be•at, took over operation on 1 January 2012.

The hall opened as Ethias Arena, named for the Belgian insurance company that sponsored it, and was renamed Trixxo Arena on 25 August 2021 when the Trixxo employment agency took over as main sponsor. The Schlagerfestival is held here annually, and the arena has hosted Destiny's Child, Tiësto and André Rieu.

The arena is part of Park H, whose grounds cover 25,000 m², with the Main Hall alone taking up 13,600 m². The hall can be reconfigured from one day to the next, and several rooms can be combined to raise capacity. The Main Hall seats up to 9,946 or holds 18,000 standing.

The Main Hall covers 13,600 m² and can be reconfigured from day to day; before 2012 it held about 21,500 visitors. On 12 April 2008 the first I love the 90's party drew over 21,000 people, then the largest indoor party held in Belgium. The arena also hosted the 3rd Junior Eurovision Song Contest on 26 November 2005.
