Philips Arena is an indoor arena in Atlanta, Georgia. Completed in 1999 at a cost of $213.5 million, it is home to the Atlanta Thrashers of the NHL and the Atlanta Hawks of the NBA. It is owned and operated by Atlanta Spirit, LLC, the group of investors that also owns the Hawks and Thrashers. The arena seats 18,729 for basketball and 18,545 for ice hockey. It includes 92 luxury suites and 1,866 club seats. For concerts and other entertainment events, the arena can seat 21,000.

The arena is laid out in a rather unusual manner, with the club seats and luxury boxes aligned solely along one side of the playing surface, and the general admission seating along the other three sides (the arrangement was later emulated at the Detroit Lions home field Ford Field). This unique layout is a vast contrast to many of its contemporaries, which have their revenue-generating luxury boxes and club seats located in the 'belly' of the arena, thus causing the upper deck to be 2-4 stories higher. The layout at Philips was done so as to be able to bring the bulk of the seats closer to the playing surface while still making available a sufficient number of revenue-raising club seats and lodges.

On the exterior, angled steel columns supporting the roof facing downtown spell out "ATLANTA" and the side facing the Georgia World Congress Center spells out "CNN." The arena adjoins the CNN Center. The Dome/GWCC/Philips Arena/CNN Center rail station below the arena provides access to MARTA public transportation.

During the late 1980s and early 1990s, many cities started building new state-of-the-art sporting venues for their NHL and/or NBA franchises, or in hopes of attaining one. Many of these arenas had modern amenities for their high-end customers, such as luxury boxes, club seats, and large, posh club-level concourses; some even had practice facilities on-site. These attractions were rarely found in arenas constructed in the early 1970s when The Omni was built and led to its chief tenant, the Atlanta Hawks being put in a competitive disadvantage. The operating manager of the current arena in place Ted Turner wanted an expansion hockey team but was told by the NHL that a new arena would have to be built. That, along with the fact that The Omni was rapidly deteriorating led to a new venue being built. After the Atlanta Hawks were eliminated from the 1997 NBA playoffs by the Chicago Bulls, the Omni was demolished and Philips Arena was constructed in its place.

Philips Arena occupies the site of the Omni Coliseum, Atlanta's former sports arena. The Omni's "center-hung scoreboard" now hangs in the lobby of Philips Arena, where it still displays The Omni's logo along with that of Philips Arena, the Hawks, and the Thrashers (who never played in The Omni). The scoreboard still functions and displays information relevant to the game taking place in the arena.
