Winterthur Central Sports Hall, sports venue in the canton of Zürich, Switzerland

The Winterthur Central Sports Hall, known as the AXA-Arena, is a ball-sports hall in the Deutweg quarter of Winterthur's Mattenbach district, part of the WIN4 campus. Its playing field measures 20 by 40 metres, the international size for handball and large-field floorball, within a usable hall area of 29 by 48 metres. A grandstand seats 2,000 spectators, and an AXA lounge holds about 300. The building was constructed to the Minergie-P standard and has a photovoltaic system.

Plans for a national performance and grassroots sport centre in Winterthur were discussed from 2006, when the Eulachhalle was often overcrowded. After a Swiss Ice Hockey ice-centre project was abandoned, private investors submitted the building application in December 2015; the foundation stone was laid in March 2017 and the arena opened in May 2018. The first official games were test matches on 3 August 2018, when HC Rychenberg beat Zug United 7:3 and Pfadi Winterthur beat Fortitudo Gossau 35:17.

The hall serves as a gathering place for sports enthusiasts and community members who share an interest in active living. Local teams like HC Rychenberg Winterthur and Pfadi Winterthur use the space regularly, bringing together fans and neighbors who enjoy watching and supporting their clubs.

The arena sits in the Deutweg quarter of Mattenbach, in northern Winterthur, next to the Zielbau-Arena ice rink and the Deutweg stadium. City bus line 3 stops at Scheidegg close by, and the campus has a public underground car park. The whole complex is wheelchair accessible.

The arena's 20 × 40 m playing field matches the international dimensions for handball and large-field floorball. In November 2022 the hall hosted 23 matches of the 2022 Floorball World Championship. The first official games were test matches on 3 August 2018, when HC Rychenberg beat Zug United 7:3 and Pfadi Winterthur beat Fortitudo Gossau 35:17.
