Amazon HQ2 is Amazon's corporate headquarters in National Landing in Arlington, Virginia and is an expansion of the company's headquarters in Seattle, Washington. Phase I, which has capacity for 14,000 employees, opened in June 2023. Construction on Phase II is delayed and there is no timeline for development.

National Landing is an area in Northern Virginia encompassing parts of the Crystal City and Pentagon City neighborhoods of Arlington County and the Potomac Yard neighborhood in the city of Alexandria. It is the location of the Amazon HQ2 headquarters. The neighborhood was branded and announced as "National Landing" in 2018 as a part of local economic development plans to bring Amazon HQ2 to the area. The announcement also included plans to build a graduate-school satellite university campus of Virginia Tech in the area. The "National Landing" name derives, in part, from the area's proximity to Ronald Reagan Washington National Airport.
