The Paris La Défense Arena (originally known as the U Arena) is a multi-use domed stadium that is located in Nanterre, which is a western suburb of Paris. It is one of the two multi-use domed stadiums to be built in Europe, along with Telenor Arena.

In Spring 2018, the arena was renamed from U Arena to "Paris La Défense Arena" following a vote by its board of directors. 

The venue offers three separate configurations. In its rugby configuration, it has a nominal seating capacity of 32,000. For concerts, it is able to seat 40,000. Finally, a movable stand allows it to also be used for a variety of indoor sports, at various capacities, with a capacity of as low as 5,000 being possible.

The venue also includes 33,000 square metres (360,000 sq ft) of office space, 300 student rooms, shops, including a club shop, a brewery and a gourmet restaurant. The arena was built by the French rugby union club, Racing 92, and replaced their previous stadium, Stade Olympique Yves-du-Manoir. 

For the 2024 Summer Olympics, in which the arena will host gymnastics events and commercially sponsored names are prohibited, the local organizing committee is using "Arena 92", a name that had been used early in the venue's planning process.
