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 was 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.

The arena is sponsored by and named for Philips Electronics and therefore contains a large number of television screens made by Philips. 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.
