T-Mobile Arena, Indoor sports arena in Paradise, Nevada.

T-Mobile Arena is an indoor venue for sports and entertainment in Paradise, Nevada, close to the Las Vegas Strip. The building holds around twenty thousand people across multiple levels and includes private suites and different seating sections for concerts, sports events, and other programs.

Construction began in 2014 and the building opened in the spring of 2016 to meet the growing demand for large events in Las Vegas. Shortly after opening, the city welcomed its own professional hockey team, which played its first home season here.

The Vegas Golden Knights hockey team plays its home games here and fans bring red and gold jerseys into the stands on game nights. Alongside hockey, major UFC fighting events and international boxing matches draw crowds from around the world who come to watch the matches live.

The building sits a short walk from the southern end of the Las Vegas Strip and several hotels connect directly via pedestrian bridges. Visitors arriving by car will find parking in attached garages, which fill up quickly before major events and should be reached early.

The arena's nickname, "The Fortress", comes from its role as the home of the Vegas Golden Knights, who began NHL play here in the 2017–18 season. The team's first home game, on October 10, 2017, against the Arizona Coyotes, drew 18,191 spectators, about 4.7 percent above the arena's official maximum hockey capacity. A record hockey crowd of 18,702 attended Game 2 of the 2018 Stanley Cup Final against the Washington Capitals.
