The Verizon Center (formerly MCI Center until March 5, 2006) is a sports and entertainment arena in Washington, D.C., USA, named after telecommunications sponsor Verizon Communications. The arena has been nicknamed the "Phone Booth" because of its association with telecommunications companies. The arena is home to the Washington Capitals of the NHL, Washington Wizards of the NBA, Georgetown University men's basketball, and Washington Mystics of the WNBA.

The arena opened as the MCI Center on December 2, 1997 in downtown Washington's Chinatown. When Verizon bought out MCI in 2006, the arena's name was changed accordingly. The building replaced the US Air Arena, which was located on the Capital Beltway in Landover, Maryland. Some complained that the building's construction, by closing off a block of G St, corrupted the historic L'Enfant layout of the Washington city streets.

Others were concerned it would lead to the displacement of Chinese businesses in Chinatown. While largely considered a commercial success, the Verizon Center was the catalyst that led to gentrification of Washington's Chinatown, with rent increases after construction of the Arena forcing many small Chinese businesses to close. On the other hand, the Arena is not only a popular venue for sports and concerts, but helped to turned "Gallery Place/Chinatown" neighborhood into one of the prime sites for commercial development in Washington. Virtually all Chinese residents in the D.C. area already live in the suburbs, and displacement that occurred over the years has been mostly commercial rather than residential.

In 2007, what was claimed as the "first true indoor high-definition LED scoreboard" was installed at the Verizon Center [1].

The arena is owned by Washington Sports & Entertainment (which owns the Wizards and formerly owned the Capitals and Mystics), but on land leased from the city of Washington. At the end of the 30 year lease, the land is set to revert back to the ownership of the city, with the mayor of Washington to make mandatory biennial reviews of the city's continuing need for the arena.

Two notable fan fixtures at Washington Capitals games at Verizon Center since the late '90s include Goat and The Horn Guy. "Goat," aka William Stilwell, sits in Section 105 and loudly stomps and starts cheers for the team, with his loud voice that The Washington Post once called "the loudest voice and stompiest stomp on F Street." [2] "The Horn Guy," aka Sam Wolk, blows out three blasts on a horn to which the arena responds "Let's Go Caps!," a chant that can be heard during radio and TV broadcasts, home and away.
