Under Armour's headquarters is located in which U.S. city?

Under Armour’s headquarters is located in Baltimore, Maryland.

The company was founded by Kevin Plank in 1996, but its earliest operations began in Washington, D.C., in his grandmother’s basement. As the business developed, Plank moved the company to Baltimore, a city closely connected to his University of Maryland background and the brand’s origins in football performance clothing.

Under Armour is headquartered at Tide Point, a waterfront complex in Baltimore’s Locust Point neighborhood. The location reflects the company’s long-standing identity as a Baltimore-based sportswear business, even as its products and operations became global.

A common mix-up is Washington, D.C., because that is where the original home-based operation began. Another is confusing Baltimore with the University of Maryland’s campus in nearby College Park. The university helped inspire the product, but the company’s headquarters is in Baltimore. The city is also associated with Under Armour’s early retail presence, including its first Brand House, which opened there in 2013.
