The USTA Billie Jean King National Tennis Center, located in Flushing Meadows–Corona Park in Queens, New York, is synonymous with world-class tennis, primarily due to its hosting of the US Open. Named after Billie Jean King, a pioneering figure in women's tennis and an advocate for gender equality in sports, the facility stands as a remarkable tribute to her enduring legacy.

The complex, owned by the United States Tennis Association (USTA), has undergone significant transformations since its original opening in 1978. Its development reflects the growing popularity and evolution of tennis in the United States. The center showcases three primary stadiums—Arthur Ashe Stadium, Louis Armstrong Stadium, and the Grandstand, each known for their distinct features and capacities.

Arthur Ashe Stadium, the largest tennis venue in the world, can house up to 23,771 spectators. It was inaugurated in 1997 and represents a major engineering achievement with its retractable roof completed in 2016. This feature has proved to be a game-changer, ensuring that play can continue undisturbed during inclement weather, particularly crucial during the often unpredictable climatic conditions of the late summer in New York.

Louis Armstrong Stadium, which opened in 2018, replaced an older structure and can accommodate around 14,000 fans. It also features a retractable roof and is designed with sustainable elements such as natural ventilation. The stadium provides a more intimate experience while maintaining significant crowd capacity.

The Grandstand, which can seat approximately 8,000 spectators, offers arguably the most intimate and unique viewing experience at the complex. Known for its smaller size and close seating arrangement, it allows spectators to feel more connected to the action.

Apart from these main arenas, the National Tennis Center includes dozens of additional courts, including practice facilities where fans can often watch their favorite players prepare away from the main stage spotlight. This accessibility is a key component of what makes attending the US Open a special experience, providing fans with a behind-the-scenes glimpse into professional tennis.

Hosting the US Open, one of the four Grand Slam tournaments, the center becomes a global sports hub from late August to early September each year, drawing in hundreds of thousands of attendees from all over the world. Players compete on acrylic hard courts, which are known for their durability and slightly faster surface speed, affecting game play strategies.

The USTA Billie Jean King National Tennis Center's role extends beyond hosting major tournaments. It serves as a public tennis facility for much of the year, promoting the sport's development at grassroots levels through various programs and events. This aspect underscores the USTA's commitment to nurturing new talent and making tennis accessible to a broader audience.

The center's ongoing improvements and expansions reflect the dynamic nature of tennis and the increasing demand for high-quality facilities. These developments ensure that the USTA Billie Jean King National Tennis watches over the interests of the sport while honoring the legacy of its namesake, who championed equality and innovation both on and off the court.
