Which tennis stadium is the main court of the US Open?

The main court of the US Open is Arthur Ashe Stadium.

The stadium is part of the USTA Billie Jean King National Tennis Center in Flushing Meadows, Queens, New York. It opened for the 1997 US Open, replacing Louis Armstrong Stadium as the tournament’s primary venue. The stadium honors Arthur Ashe, who won the first US Open of the Open Era in 1968 and became a major advocate for civil rights and education.

Arthur Ashe Stadium seats 23,771 spectators, making it the largest tennis stadium in the world. A retractable roof was added for the 2016 US Open, allowing play to continue during rain. The complex also includes Louis Armstrong Stadium, the Grandstand and numerous smaller courts, but those are secondary venues rather than the tournament’s main court. Court Philippe-Chatrier is Roland-Garros’ principal court, Centre Court belongs to Wimbledon, and Rod Laver Arena is the Australian Open’s show court.
