Louis Armstrong Stadium
|Location||USTA Billie Jean King National Tennis Center, Flushing, Queens, New York City|
|US Open (USTA) (2018–present)|
Louis Armstrong Stadium is a 14,000-seat tennis stadium at the USTA Billie Jean King National Tennis Center, one of the venues of the US Open. It opened for the 2018 US Open as a replacement for the 1978 stadium of the same name.
The stadium has a retractable roof, the largest of its kind among the No. 2 stadiums at Grand Slam venues. At the time of its opening it was the 13th largest tennis venue in the world (based on capacity). It is the first tennis stadium to have a roof and be naturally ventilated. Designers say the terra cotta material contextually relates to the traditional brick buildings on the site while using the material in a new way.
The stadium was opened on 22 August 2018 and John and Patrick McEnroe played an exhibition against James Blake and Michael Chang. The first official match was played on August 27th, 2018 between Simona Halep and Kaia Kanepi. Kanepi won in two sets, which was the first time a WTA No. 1 had ever lost in the first round of the US Open. 
For the 2017 tournament, while construction was still ongoing on the new Louis Armstrong Stadium, a temporary 8,800-seat stadium was built on the site of the demolished ticket office and East Gate entrance, on Parking Lot B, close to the boardwalk ramp to the subway and LIRR trains.
